Tomtom dropping GPS - Touch HD General

Using TomTom v7.450 (build 9028) the device can work fine for hours, but sometimes I start Tomtom and it will find a GPS signal and then immediately drop it again.
When I look at the satellite information, it will do this...
1. No GPS device!
2. Poor signal, are you indoors?
3. Built-in GPS receiver
4. No GPS device!
5. Poor signal, are you indoors?
6. Built-in GPS receiver
7. No GPS device!
and repeat..

Hi, I've the same problem on my Blackstone, GPS works well for days bu from today the GPS signal result discontinuous with any navigation software like Tomtom(various versions), Trackypro and iGO8...any idea? Thanks

I had the similar problem when I first installed TomTom. Which settings are you using? Because I used "built-in GPS" for TomTom and had the above problem. When I changed it to "Other NMEA GPS" with baud rate at 11200 ()or whatever the max is + COM4 then gps started working like a charm. Since then no signal drops, no lag and very quick fix. Not sure if it is just by chance or is it a real fix for the above problem, but worth trying as its working for me. However, it has been 2 days only. Not sure if after a while I will have this problem or not. I am using Tom Tom 7.910 with maps 6.75.

Can You try to set the hardware port from <None> to COM9? Seems work better, the GPS signal still present...but for now I'm at home

I have more or less the same problem !
Using TomTom v7.450 (build 9028) the device works fine the 1st week, but now, I start Tomtom it xan't find GPS device !
I tried to reinstall all without success...
I also tried all the COM available !

using tomtom 7 with NMEA com 4 max baud rate. Works just fine. 8 or 9 sats locked on constantly in open areas

I'm having the same problem, although I don't have TomTom 7. But it doesn't seem to be just TomTom that's having trouble finding the GPS (and when it does, it'll never get a fix).
The Google Maps application also gives me the "No GPS found" attitude.
I've installed the HTC GPS Tool, which does seem to find a bunch of satellites, but they all stay no-fix-reddish.
Are there any guidelines on how to setup the GPS on this thing? I find it a bit strange that my settings menu only lists an option "External GPS", and no "Internal/Built-In GPS".

Can confirm that the dropping of GPS is in other applications.
I use zürich map from Lonely Planet (sure its form 2003) and it will drop the signal in the open.
Have a feeling its internal on our devices.

One possibility is A-GPS.
It is Disabled by default, but it is possible that with tools like HD Tweak or Advanced Config Tool, you, even by being unaware of it, you activated (or better : enabled) it.
To me, it was a winner : after re-disabling A-GPS, my GPS started to be stable again, no matter what port I choosed and how I configured the Navigator program.
Give it a try, could be the solution that works for you

Hi there,
I've just picked up my lovely HTC Touch HD - I'd like to buy the TomTom 7 and the correct maps to go with it to allow it to work.
Can someone please tell me where I can go to stick my Visa card details into and buy please! i'm pretty confused on the TT website and on here there's allsorts of version numbers etc mentioned!
I'd just like to have a stable running TT on my Touch!
Any chance of also having the US & Canada maps working as well as the UK maps ?
Thanks !
Dennis! West London UK!

This is not a TomTom issue. I have same problem with IGo and VisualGPSce.
I use to resolve this issue this way (in IGo or VisualGPS) : I change the baudrate in GPS configuration. Switching 19200 to 38400, or reverse, or whatever : the GPS locks and is stable after few baudrate switches.

Theres some reports that the default "sleep" timeout for GPS is 1 second. Apparently the Microsoft Intermediate Driver only updates every 1 second so it could just miss it and go to sleep!
Try changing registry entry to 2000 (milliseconds)...
HKLM->system->currentcontrolset->GPSIntermediate Driver->Drivers-> SleepOnNoData

Already did it (currently set to 2500). But changes nothing (even after soft reset) : GPS keeps deconnecting/reconnecting as described (not every time; one in a while..).
Thanks anyways !

Just out of interest, do you have MobileJustice installed by any chance?

Absolutly not. Nor any software of this type, nor any software who can possibly take GPS in background..

I had the problem of TomTom getting satelites and then dropping them and saying it couldn't find the gps.
Disabling agps (quick gps) via advance config seemed to sort out the problem

AGPS is *not* quickGPS in my understanding. But this is unclear. For a proof, AGPS comes disabled by default, but quickGPS works out of the box. Can someone who knows for sure, precisely state if AGS and quickGPS are the same thing or not ?
I have disabled AGPS also with HD tweak (but quickGPS stills work..), and I have regulary (2 out of 3 times) this problem.

I had the same problem. Disabling the AGPS seems to have worked but I will wait for the data to expire before confirming.
The problem seems to be when I have poor GPS reception AND poor GSM. They seem to be calling upon each other for corrections but never resolve.
If this is the solution I will just rely on QuickGPS alone which has worked fine for years with TTN6.
Edit: I can now confirm disabling AGPS solved my problem.

had TTN7 running for a few days now.
Can't find the built in GPS. Having to set it to other Bluetooth GPS Receiver.
A bit hit and miss with signal / getting a fix.
I have turned off AGPS as well. Going to try out some of the settings you all have put up tomorrow.

HP Ipaq 614 GPS don´t Work.

Hello!
I have a Ipaq 614C and I have a problem. When i install the TomTom i can't connect to the GPS. In the HP asset's it appear GPS: Present but in the status appear disable.
Anyone can help me.
Thanks.
John
Check in TOMTOM which GPS com port it's using. Then change to same port
as set in Settngs->Systems-> External GPS -> Programs com port.
I dont use Tomtom myself but I've used so far Google Maps and NAv4All and it works fine without any changes.
Good luck.
On my ipaq 614, the default com port for the gps is port number 6. And it works fine with that.
im also having some GPS difficulties with 614c: i already tried it with igo8, tomtom navigator and latest google maps. it finds satellites very slowly and rarely, mostly never. anyone got an idea?

did u try always out of the house in a open space?
most of the ppl don't know that u don't have GPS signal in close space.
second of all, first download with quick gps latest infos, after that start igo, it will be more quicker ...

Hi all, mine did not come with any quick GPS installed, the older (tomtom related) version from the 6915 does not work on that device any longer, where did you get quick gps? or is it hidden somewhere..? Since there is no navi software installed, only google maps..
txs
From my personal experience with it, it took absolutely FOREVER to connect to a satellite the very first time I tried. Took about 7 "cannot find a signal" messages before I finally snagged one.
After that, it was ~20 seconds to connect every time.
I really dont know what the deal was, but after that initial connection it seemed perfectly fine.
So my advice is, try again for a little while.
I also have problems with GPS on HP 614c. But the problem probably not in the chip, and in programs as Oziexplorer and Google Navigator satellites catch and precisely defines a site, and Navitel works through time and that in a minute satellites as though fade and data cease to be updated, Garmin in general satellites does not see. Firmware update has not helped. Anybody has ideas?
p.s. sorry for my english
With program Navitel has understood, the reason was in program MultyDID, it blocked access to keyboards and deformed a signal from satellites, Garmin does not function.

I agree with all these comments and the above regarding open space. GPS does indeed require a clear view of the sky... but one thing not so often said is that GPS needs a clear view of the NORTHERN sky... most of the GPS satellites are in a geostationary orbit above northern part of the planet.
To the guy who has tried leaving the phone on the balcony... I suspect your balcony is south facing (very nice).
I have also found that the longer it is since your last fix, the longer it will take to get a fix. GPS satellites only broadcast their "here I am" messages every 30 seconds and it is mostly down to luck whether your phone is listening for the right satellite at the right time. That's why it takes a while to obtain a GPS fix on all devices. QuickGPS and other software tries to expedite the fix by allowing the phone to calculate which satellites will be the right ones to listen out for, based on a daily positions log of the GPS satellites (called ephemera data).
GPS does work quite well on the 614c (I use tomtom 6.3 and Google Maps, both extensively)... but it does often take a long time to get a fix - sometimes even 10 minutes.

Very nice. I woud've never thought about that. However, i think geostationary orbit is when the satelite goes around the equator with the same angular speed as the rotation of the Earth. So these satelites actually go around in an orbit perpendecular to the equator. Yesterday i tested and got 2 satelites inside a room with north windows. Very cool. Do you use quick GPS. I installed it and downloaded the data for the next 7 days. I didn't notice any improvement. I use DESTINATOR 7 and Maspware GPSmeter 5.I don't really get it - who manages the data downloaded by Qgps - windows drivers or the gps software itself.
More GPS thoughts
Axlastro - the ephemeris data that QuickGPS and other programs download is nothing to do with Microsoft/Windows or with HP. It is official data on the positions and movements of the satellites in the GPS network. Provided ultimately by some government department, probably American.
If you have not noticed an improvement over a period of several days, I'm not sure why this is. This old posting might help you.
Ephemeris data is also actually transmitted by the satellites themselves. This is why, when you have recently had a fix, it is usually quite quick to get another one. Programs like QuickGPS are only therefore useful if it's been a while since your last fix.
Thanks. I googled the topic and got some detailed explanations.
http://wmexperts.com/articles/gps_vs_agps_a_quick_tutorial.html
I also found a thread that says that QUICKgps doesn't work with the ipaq.
http://mobilitytoday.com/forum/showthread.php?t=16767
So that's why i don't see improvement. However neither of the people on that forum has managet to improve their fix times. Can you tell me wich program exactly you are using?
strange. i never had problems with gps. very fast . newest firmware from hp site ,and 3 different roms,original 6.0 and 2 roms with 6.1 . Igo,garmin etc.
Some more info
Really. Which program do you use, so i can try with it too.
I spoke to HP support and they said that it depends on the GPS software if it will use the aGPS function, so we have to check if the software we use is compatable with tha Qualcomm 6820 gps chipset of the ipaq.

Now update the app

Now update the second app but on this update you will get at 79% a fail note
Ignore it and check your GPS...
from my testes you will get a better hot fix (time )
If you are after SR or cold fix update the second app (the one that fails)
Good luck

Assisted GPS Pharos?

The Pharos is supposed to have AGPS. Do they mean QuickGPS or is there really AGPS on it? Where can I find it on the Pharos?
I have the WM6.0 Dutch version.
when i turn on tomtom in my house it says im in the location of the nearest gsm beacon...before i have a satellite fix, thats assisted GPS i think...
quick gps only has the trajectories of satellites in the "local" sky so the gps chip can get a fix quicker
Strange, nothing happens when I start TomTom.
Can you give me your settings in the register:
HKLM>Software>HTC>SUPL AGPS>
i checked but no such key
wat is the setting of your key?
Keysetting in HKLM>Software>HTC>SUPL AGPS> is:
(Default) (value not set)
EnableAGPS 1
EnableGPSSmartMode 1
GPSMode 2
NumberFixes 389AC9FF
QosAccuracy 32 (50)
QosPerformance 59 (89)
ServerIP 195.207.101.126
Serverport 1E6C (7788)
TimeBetweenFixes 1
When I first started with the Pharos there was no AGPS, also not in the registry the Supl AGPS. I found a registry-entry for the Pharos on this site and put it on the Pharos. When I start 'Advanced Config' from Schaft I can see under GPS that AGPS is enabled.
When I start TomTom 7.9 there's no start of GPRS. Also my GPRS monitor sees no action. So I presume AGPS is not working.
Maybe I need some dll drivers, I don't know. Can somebody help?
you have a confusing story
first you talk about GPS and then about GPRS
these are 2 different things
GPRS is your data connection (in case EDGE is not available)
GPS is global positioning system and i didnt know tomtom 7.9 was out, i use 6.
if you do a simple search on the phorum you can see that tomtom 7.9 causes a few problems i suugest you read that!
my advice would be to revert back to 6 .. works great on the pharos
Maybe I'm confused. I thought Assited-GPS uses GPRS to make contact with the gsm beacons and so make a faster fix with these beacons. Am I wrong about that?
The builtin GPS from the Pharos works fine but is not very fast with the first fix. I thought AGPS would help making a faster fix.
I already had TomTom 7.4 and know 7.9 (cracked version). Works fine on the Pharos. I will look for the problems with 7.9 on the forum.
Thanks
hmmm yeah makes sense we do need a server to relay the info... but ive looked it up
http://en.wikipedia.org/wiki/AGPS
http://en.wikipedia.org/wiki/List_of_devices_with_Assisted_GPS
our device is on the list... but i dont think i have a server setting... and my gps (tomtom) doesnt have to have a connection to the internet.
strange but fun to find out how it works...
TomTom does not use the AGPS function. Enable quickgps to do this before you use your navigation software (TomTom). It can automatically download the satellite info for you which is good for about 2 days. You can update through your cellular connection if you have data on your plan or through activesync. TomTom 7 will work without using the AGPS function but it will take longer to find a fix on the satellites. TomTom 7 is required if you want to use the internal gps receiver with TomTom. TomTom 6 does not work without some hacks.
I think that Google Maps do use the AGPS function. It is much faster to find the coordinates than fx TomTom and other GPS software i've tried, so i think that a program needs to be developed with use of the agps function if it uses it..

Xperia GPS malfunction

Hi
I wonder if someone has this same problem and know how to solve it...
Most of the times that i try to use tomtom or wayfinder, the gps can't get a fix, it locks on to the satelites with no problem, but only for 1/2 seconds, then loses the position and after some 10s it regains the position again for another 1/2s and loses it again...
The only i way can get the gps to function properly again is by turning the phone off, remove the battery and turn it back on. Then it works, but if i turn off tomtom and try to use wayfinder the problem returns, and sometimes also happens after i close tomtom and try to use it again later...
It's driving me nuts i did a hard reset and after instaling my programs the problem remains. It seems google maps works ok, tho i'm not sure as the program doesn't have the option to see to how many satelites it's locked on.
any ideas? I doubt it's from the programs i install cause the ones i use i dw them all from this forum...
Thanks
its probably your location, the satellites might not be abundant enough. GPS works fine for me, I'm using IGO8.
no, it's not that, cause when it happens i remove the battery and reinsert and turn on the phone again, and after doing that procedure the gps will lock with some 6/7 satellites and will not fail as long as i don't turn off the first program i try to use the gps with ...
If i use tomtom after doing that battery removal procedure, it will work flawlessly, if i turn off tomtom and use it right after, it still works ok, but, if i turn off tomtom and after i use wayfinder, or if i only use tomtom again after some hours, it will have that problem (and vice-versa), it does find the same satellites and gets the coordinates (in tomtom they get those blue level bars), but only for very brief moments every 10/15s which ofc makes it impossible to correctly use the navigation program
If the gps was broken or something it wouldn't work ok after i removed the battery... i guess i'll try another hard reset
Try to disable A-GPS.
possible corrupt quick gps file , run quick gps and downoad new file.
Hi,
If you have used Advanced Config and enabled A-GPS, disable it as it will cause issues with TomTom and other GPS navigation software.
Later...
hehe got it working now, i had tried that before, but seems i was using an older version of advanced config or something, i downloaded a new version, disabled a-gps and now the gps is working fine thanks for the help
Re elusivo
Elusivo, could post how you fixed your problem? Because I currently have the same problem, but no Idea how to fix it. You said something about using a new configuration with and old one? Can you please explain?
Search for the program 'Advanced Config' on the forum and install it and then run it. Go to the GPS section and if A-GPS is enabled disable it. A-GPS uses the phone masts to triangulate and get your position which causes havoc when you are trying to use the internal GPS
Thanks for that......Problem solved
hello
I do have the saame issue as you with my gps. I install Igo, tomtom, gps htc tools and gps skinner and it is always 20/30sec to get a fix but it loses it 1 sec after.
If I disable A-Gps, it will increase the time to fix satellites or is it just used for quiick gps to download ephemerids???.
I think we have to ask Customer support because it is unacceptable for such an ewxpensive phone to have to disable functionalities such as A-gps to get it to work

A-GPS uses Cell Towers to guess where you are. It is not (on these phones anyway) linked to Quick GPS which is a lot better at getting you a fix on a cold start.
As others have mentioned for some reason with A-GPS enabled TomTom doesn't like it, and I don't know of any real reason to use it.
@artesea : I don't get why you said "I don't know of any real reason to use it".
Are you talking about Tomtom or about A-GPS function ??
Because if you are speaking about Tomtom, I do have similar problem with all software using GPS.
And if you disable A-GPS function you are going to have to wait may be 3 minutes or more to get a fix instead of 40seconds so I think this is a real reason to use it...
No I'm talking about A-GPS.
Have you tried a cold start using Quick GPS, I can get a location in under 30 seconds.
So I disable A-GPS and I got fix within 30/40 seconds and I never lost it.
I just think it is absolutely unbearable to have to disable A-GPS to get your GPS working properly. This mobile phone cost 700€
I just would like to know what is protocol version from people who can have A-GPS working properly.
Rom version : 1.02.933.3
Radio version : 52.43.25.24W
So you've gone from 20/30 seconds to get a fix but then it drops, to 30/40 seconds to get a fix and it work and you STILL have a problem???
Maybe there is a reason why A-GPS is disabled by default!
No when I disable A-GPS I don't have problem any more.
I just remembered that I may have enable A-GPS through Advanced Config.
Hard reset do not change this, I though it was a registry editor value but apparently it is more than that.
Anyway it is not Xperia X1 issue but Advanced Config compatibility with Xperia X1
having problems with gps now too :/ later it was working brilliant (fix in no time), but now, most of the time i dont even see any satellite...
but sometimes, especially after reset, it shows like 5-6 satellites, but cant get fix, after some time sats just disappear :X tried disabling/enabling a-gps, with/without quick gps file downloaded, still the same... and no answer anywhere...
i guess i'll have to use my warranty and get it serviced :/
edit: today reflashed radio one more time (as yesterday after like 5 radio flashes, i ended on the original version, not the newest one) and suddenly gps is working hope it lasts...

Orange UK AGPS settings

I'm trying to get AGPS working on my blackstone and like other people have found if I turn AGPS on the GPS keeps dropping out.
I think this may be because of AGPS settings in the HTC ROM I'm using (HKCSL_WWE_1.19.831.0) having a non Internet routeable server address 10.1.101.63
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"ServerIP"="10.1.101.63"
I'd like to try it with working AGPS settings for Orange UK's AGPS server.
I think I know the server name is "agps.orange.co.uk" but I don't know the port number, has anyone got a phone with a standard Orange UK ROM and could check the settings for me?
The ones I need are:-
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"ServerPort"=
"ServerIP"=
"ServerURL"=
"GPSmode"=
Thanks a lot
Peter
Are you still looking for these settings?
I have a vanilla Touch HD ..
Let me know where to find the settings and I will give them to you.
Hi yes still looking for the settings.
To get them you'll need a mobile registry editor either on the phone or on your PC
Then the settinsg I need are in:-
HKEY_LOCAL_MACHINE
Software
HTC
SUPL AGPS
And the actual entries are (not all of them may exist):-
"ServerPort"=
"ServerIP"=
"ServerURL"=
"GPSmode"=
If you can get them for me many thanks
Hey there,
I'm on a standard Orange UK ROM. Mine is as follows:
"ServerPort"=7275
"ServerIP"=10.1.101.63
"ServerURL"= (not there!)
"GPSmode"=2
Hope it helps!
Ah right thanks.
That probably explains why AGPS doesn't work for most people if they enable it makes the GPS drop out.
The settings look like they're internal test ones used at HTC, the IP address 10.1.101.63 is the same as in a stock HTC ROM so can't point to Orange's agps server.
Thanks for checking for me, I'll have to carry on searching I think
Have you tried agps.orange.co.uk port 7275?
Hi, that does look better after a very quick test, TomTom isn't saying "No GPS device" every few seconds with AGPS enabled.
I'm indoors at the moment though, so I'll have to give it a proper test tomorrow when I'm out in the car
Thanks
No, just tried it in the car and it's still dropping out to "No GPS Device" with AGPS enabled, disable AGPS and it's OK again
Looks like AGPS just doesn't work properly
Thanks for all the help anyway
There are several threads where AGPS has been a problem.
A fix is achieved by the receiver, AGPS and QuickFix. In my view AGPS causes conflict where a low cell tower signal is present. Isn't AGPS achieved by a rough triangulation from cell towers?
Disable AGPS with HD Tweak and let upto date QuickFix data do its work just like it did on TTN6 on other devices without problems.
Get your first cold fix outdoors, stationary and with clear sky would be good. This may take a few minutes. Subsequent warm fixes will be much faster.
The HD receiver is not as sensitive as a SirfIII IMHO but it does work fine.
Yes, I agree AGPS just isn't working on the Blackstone, at least for me.
I've only just got the Blackstone to replace a Kaiser and I've noticed the GPS on the Blackstone gets a first fix a lot faster than the Kaiser used to.
On the down side though TomTom 7.910 on the Blackstone seems to suffer from much worse lag than TomTom 7.450 used to on the Kaiser, perhaps it's just that it's driving five times the screen area perhaps.
The "lag" for me is one second. Which is the refresh rate of TomTom Navigator. No significant difference from my Artemis with v6.
No not select too many POIS for display as this effects the redraw time.

I have just got it working on orange uk using the following
IP address: 194.51.71.162 - found by pinging agps.orange.co.uk
port: 7275 - looking around the forums, most mobile providers seem to use this port.
i deleted the serverURL key, and my gps mode is set to 2 or 4(this tells it to use cell location and the orange server)
With these settings, my tomtom software first (after about 20 secs) goes to the center of the local orange cell, showing five satellites which are actually the agps "pretend" ones. It then picks up the real satellites and my position moves to the correct gps position. I never had much issue with the position from the standard gps signal, but the altitude reading is now much more accurate, showing the agps is having some effect (no idea why I would need an altitude reading?!?)
Whilst the tomtom software works perfectly, my memory-map software crashes when it tries to load with agps turned on. If another program (ie tomtom) has already initalised the gps, then memory-map also works fine.

Optimal GPS settings for faster GPS lock on HD2? (Also using GarminXT)

Hi all,
I didnt want to start a new thread, but after searching the forums and google for a long time, i decided to bring it up
So ive had my HD2 for about 2 days now, and I recently installed GarminXT (I used to have it on my Nokia N82)
the problem i'm finding is that the GPS doesnt lock as fast as i thought it would be..
GarminXT has not been locking on (little over 5 minutes now)
I'm a noob to Windows Mobile and HTC so please bear with me!
1. How do i know A-GPS is working? Is it automatically enabled? (This wasnt the case for Nokia as you could manually turn off A-GPS and use strictly GPS signal). Under Location settings i have "Location Service Settings" = ON
and HTC Location Service = ON
2. Im still not 100% sure what QuickGPS does. I've read about it , but all i concluded was that it uses your data to get a faster GPS lock.
So i tried running QuickGPS and it updates no problem.
I open GarminXT and it doesnt lock on. Do i need to use this?
3. Can someone tell me if these are the optimal GPS settings? I kept searching around the forum but cant find one specific to the HD2.
So under "All Settings" > System > External GPS
Programs Tab > GPS Program Port = COM4
Hardware Tab > GPS Hardware Port = None > Baud rate = 4800
Access Tab > Managa GPS Auto = Checked
Are these settings correct? Or are there "tweaks" to it that I can change?
4. One last question:
Under GarminXT, i have the ability to choose 3 GPS options:
"Use Bluetooth GPS"
"Use GPS Intermediate Driver" = Checked
"Use Serial GPS" > Once selected, i get 4 other options to choose:
COM1: Bluetooth Serial Port
COM2: Bluetooth Serial Port
COM4: COM4:
COM9: 7500 COM port
Does anyone know if i should be checked on "Use GPS Intermediate Driver" or if i should be checking off "Serial GPS" > COM 4?
This is my first WinMo device with a data plan (I'm on EDGE speeds cause I'm in Canada), but I always had the impression AGPS would really help the lock times.
Anyone with help would be GREATLY appreciated!
Again, loving the new HD2
Thanks
For GarminXT, use intermediate driver.
For Google maps, use Com4, 4800 rate, that enables use of the compass.
Quick GPS should increase startup, and so far I had all fixes on HD2 under 30 seconds, and I did not change anything.
Normally GPS would download information about orbits of satellites from the satellites. That can take time, as it is one way communication and GPS can't ask satellite to send data again in case of error, it must wait untill the satellite starts sending them again by itself.
It is much faster to get that data via network .. and that is exactly what QuickGPS is for. Problem is that at least on my previous X1 there were many problems with it. The data from network was sometimes completely wrong, and you had to delete the file manually. That information is in temp\xtra.bin. Try to delete it and try again. QuickGPS does not test existence of the file, it will download new one in predefined time.
I'm still a bit confused about aGPS. I'm not sure what it is. Some people state it is the same thing as QuickGPS. Some say it is something to get quick basic fix based on BTS. But I haven't seen that in any application, except Google maps, and they seem to use their own technology and data for that.
But AFAIK, those 'location services' is generally Google's 'my location' exposed for other HTC applications.
I set it on max rate, do i do a mistake? I think that this is setting the speed or Im wrong?! Im connecting with sattelites below 15sec, with no other tweaks or quickgps...
^^
what's "max rate"?
btw, thanks for the replies
i'll look into deleting the cache file for QuickGPS and see if it does anything
Quick GPS allows you to download a weeks worth of GPS satellite position data (almanac data) at one time, helpful if for example you don't have a data plan - you can get your A-GPS data in one hit over WiFi. It helps speed lock time.
Not sure what is happening with yours, mine always locks in Garmin within 7-15 seconds, I have Quick GPS set to autoupdate, but otherwise no special tweaks or modifications where GPS is concerned.
Same here - in fact, the HD2's locking faster to GPS than my Touch HD ever did. I'm getting locks in the garage now whereas before I had none with my Touch HD. Haven't touched the default WM GPS settings or the Garmin one at all since I upgraded to the HD2.
GPs lover-Google map hater
Hi guys, firstly thanks for this thread as i too look for answer...and find some only here
i had the Diamond and now the HD2 and share the love.
Garmin maps are much more accurate and have even the smallest unpaved roads which Google map lacks. Google is so basic maps, i simply hate it...sorry Google...not to mention that it cost money to be online all the time
HD2 GPS confuse me. Sorry if I ask u basic staff but could not figure it up myself:
1. using the GPS w/google map, how u set simple setting, as: "north up" or ""track up" Route setting such as "faster time" or any other basic settings that I always had on my Garmin GPS including Garmin mobile XT?
2. What happend to voice navigation wiith google?
3. Reading your info, does it means that I can install Garmin mobile XT I got with Diamond on HD2 ?
4. Anybody know TomTom for HD2 (which I will get shotly from HTC?
I trust someone out here is smarter than me and will come to rescue
hey guys,
my HD2 is fine now, usually i just do a QuickGPS connect before opening Garmin XT and now it connects SUPER fast...usually under 10 seconds
Thanks for all the help!!
Google is not, and does not set out to be a full satellite navigation prpgram, so it doesn't have stuff such as 'North Up', 'Track Up' etc, nor does it have spoken directions.
For these you need a dedicated SatNav program like Garmin, TomTom, CoPilot or iGO8 which are all 'paid-for' applications.
TomTom will run fine but TomTom don't officially support it, meaning you can't download the correct vesion direct from their website. There are easy ways around this though!
With regard to some of the earlier posts- the HD2 can aquire a fix faster than any other device I've used (and I've used a lot!). I find QuickGPS makes very little difference, but as it uses only a small amaount of data I keep it updated.
QuickGPS and A-GPS are not the same thing, though there are quite a few different definitions of A-GPS. Genuine A-GPS is not used in UK, nor as far as I know anywhere else in Europe except by dedicated programs and platforms set up with the infrastructure (such as Apple, who use it to enhance the poor performance of the iPhone's GPS chip). It is used in the Far East, and works by enhancing your accuracy of positioning by using the data channels to send your current cell ID plus any other availble stuff like WiFi hotspot info, which is correlated to a database of locations, and sent back as an approximate position to the phone. Google Maps uses something like this if a GPS signal is not available- the 'Locate Me' feature will show you in a radius of around 1km.
The Baud rate makes no ostensible difference to the lock times or accuracy, as the data stream from the satellites is far lower than even the lowest baud rate. The NMEA default is 4800, and most software is happy to connect at that rate.
The google maps GPS finds me within 80 metres.. that's not accurate right? cause it puts it on wrong street technically.. When I first got it it did 800 metres =/
WOW, that was fast, thank you NeilM.
I will get Tomtom for free from HTC as it is included with Thai purchaded HD2.
Meanwhile I will try to load Garmin XT that I got with My Diamond at the time, let's see if the activation works...
As for Goole, well, I get 60 meter accuracy at the best, that make ones totaly lost in a city and for sure miss a turn, what a pity.
Thanks again for ever so fast reply.
When Google Maps is started it is finding your position throught the carrier's network and that is why it is not acurate at all. There is an option however, named "Use the GPS" in goolge maps and it becomes as acurate as any other navigation software It just have to engage an GPS lock as the others so do not blame google on this one Hence, you are not using the GPS when you get the inacurate positioning For the maps however you still have to be online But if you pay for your Garmin, iGo maps it would be that expensive and you can use it wherever you are ...
You absolutly right. i did use the "use gps" and it's accurate. The thing is that as heavy GPS user the lack of detailed info on google maps, and the inability to set the maps at your convinient (such as "track up" for example) it's nearly a secure way to go crazy while nevigating, specially off road...try to tilt your head to understand your position in real time when you turning and turning. Thanks for the gps tip.
I agree. Curent version of Google Maps is not suitable for navigation while driving indeed! It can help you get orientated sometimes or if you are looking for something big iGo and Garmin are in a whole new league of navigation sofware for now. However, the new version of Google Maps should be at least as good as the others but it is only available for Android at the moment and I dont see it coming to WM any time soon so we will have to stick to iGo, Garmin, TomTom and the others. I'm not using Google Maps for navigation at all by the way so It wouldn't be so difficult for me )

It's called google navigation, not google maps - and it seems to kill every GPS program available today (thank god).
hey guys,
on the same topic, but different nav software. i use iGO 8, can someone please tell me what the optimal setting are for port and baud rate? i did the auto-detect and the signal is a little on/off.
also... is there a way to get iGO 8 to use the HD2s compass? i like the stand-alone compass of the HD2, but i think it would be swell to be able to have iGO's compass function working aswell.
sorry if this has been discussed before, if there is another thread i should be reading... please direct me there.
thanks for all your help.
cheers.

Eh, if I'm not wrong, that's agps at work.
It'll find you with the nearest base station. then slowly try to triangulate you. Normally, you'll be in an area with only 1 base station, so there's not much triangulation going on.
When I'm in city, it's pretty accurate. I get my approx distance within a couple of seconds, wait another 10 - 20 secs to get gps fix.
A-Gps and other things
A-GPS is just one thing: Assisted GPS. It is a toggle-- when you toggle it on, in your phone's settings, you will get the locational assistance of the cell towers. That is the towers them selves, two or more towers and your phone triangulate to give an approximation of your location. GPS also uses triangulation (derived from simple trigonometry equations) to determine your location and is much more accurate. In fact it can be ever more accurate as your device locks onto more satellites. I have found that the best thing to do is to turn off A-GPS. I don't know what it is but Googlemaps seems to have a terrible time locking onto satellites on Windows Mobile. But I have found, especially on Android 1.6 and above you get very rapid locks so long as you wipe out the telenav program. I strongly suspect that Google is undermining Windows Mobile in favor of supporting their Android system. They have turn by turn for Android but not for Windows Mobile and it seems like they are also building it not to lock sats nearly as well. You can force it to get moving by pre opening the GPS or other methods just prior to running google maps.
I think everyone should write google and tell them to fully support Windows Mobile (Phone)... T-Mobile is just about set to come out with the HTC HD2 in about a week (March 24th) and I intend to get one. I am not happy that it doesn't have a physical keyboard cloned from the Touch Pro 2, but I expect to like most of the rest of it.
Turning Location on is another thing. You are henceforth allowing all applications to know and your location. this can be helpful but it can also be a potential privacy risk. Of course it's easy to turn off and on. You might want to read the fine print.
Actually, I have a more basic question. Is there a soft "switch" or software application to actually turn the GPS on? On my HD2 I have a few GPS apps and all of them report the GPS being on or "no GPS Device found". Even Goggle maps, if I siwtch to USE GPS mode, keeps endlessly waiting for a GPS signal and then nothing happens. What am I doing wrong?
Thanks much
Gps htc hd2
In my experience with windows mobiles and internal gps, manage gps automatically is best and no ports should be assigned at all unless using bluetooth gps receiver! Also, sounds crazy too many but no every location on this big earth is withing available to public gps devices gps satelite paths (satelites going around the earth!) Make sure your outside the house or flat before thinking your gps ain't picking up. My hd2 is fast, my old mda3 was too and worked better inside but thats down to i was living in a different location at the time and at an higher altitude i would say. 1 of many other reasons could be that the military could be using the sat at the time which would render it unavail to public (offline)!
