Tomtom dropping GPS

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.

AGPS off - Using COM 4

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.

Lag often 4-5 seconds here - Possibly all the speed camera POIs in London, where I live

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.

offline GPS for Touch 3g?

I would like to know if theres a gps program which i can use offline with the built in gps of my touch 3g. right now i use google maps which always tries to connect to the internet.
Does anyone know a well working alternative?

Check this: http://wiki.trekbuddy.net/index.php/Main_Page

offline gps?
Of course there are tens of them..
OFFROAD? ONROAD??
You do not mean Offline GPS..
You mean internet Offline GPS, I am sure..
The below are onroad ones;
TomTom, Garmin, IGO8 and many others with their own mapdatas...
Offroad ones;
GPSTuner, Trekbuddy and so goes on....
You may choose one of them depends to what city/ country you live in?

thx for answering
right now i use google maps which always tries to connect to the internet

i wanted to ask for non-internet-based gps programs, a program which doesnt need an internet connection.
Trekbuddy is Java based but for now a bit complicated (im dumb in that topic), GPSTuner looks easier so i would go for that one for now.
I live in south Germany (near Swiss boarder) so if you can suggest another nice and easy to handle im thankful.
Btw can we use Garmin on the Touch 3g with the built-in gps?

Understood. You can use TomTom for example, which is a full navigation software. Works great! TrekBuddy is quite tricky. Just found it on the web - but did not understand it neither

I downloaded TomTom "Version 7.450.9028_repack3-qvga-black", is the Touch 3g qvga anyways? ^^"
Btw I noticed that there are no maps included, maybe you know where to find a decent one for Germany??

Hello
I would suggest you to find the tomtom version 7.915.9196 (from HTC Iolite) wich works fine for the touch 3g.

I'm using mapking + Malaysia map.

thats the kind of program i mean, easy and simple.
Too bad it's maps are only for Asia, what I need is western Europe/ Germany.
thx anyways

It sounds like you have all got various form of GPS software working.
I have just got my new HTC Touch 3G on Orange UK and want to run some logging gps software.
Can you advise the corrrect settings for the GPS com port and Baud rate.
At the moment I do not seem able to talk to the GPS and the manual is not helpfull at all.
I am trying Com 4 at 4800 Baud which appears not to work..
Any suggestions ?
Thankyou

What software are you using for your GPS? You need to have a software( pre installed when you bought your HTC 3G or bought separately)
I am using Garmin Mobile XT which came with my unit when I bought it.
Then you have to buy maps too, I have Thailand Map (also pre installed)
and Philippines map, downloaded free from website.

Im using the same like you, Com 4 and 4800.

Dont underaestimate the "do it outside" rule, inside a room, even in front of the window i wouldnt ever get a gps signal, once outside it works well and fast.

1. GPS Logging Software: GPS Cycle Computer (freeware)
2. COM and BAUD are correct - run QuickGPS before! This will download some basic information via your GSM-Cells about where you are more or less. Then the GPS Signal will be found even quicker.

GPS not working on Diamond2

Hi,
I have no GPS signal with my Touch Diamond 2. But I don't have TomTom, IGo or something else. I just want to get the GPS signal to use in QuickGPS. But there is no signal at all. Does anyone know why?
And where can I configure the internal GPS antenna? Is that possible?
For testing I downloaded and installed odgps (outdoor gps), but it get's also no signal. In odgps I have configured COM4 with Baudrate 4800. But no signal. Does anyone know how I have to configure GPS programs to get them work (as said, I cannot find a screen to get or set the configuration of the internal GPS antenna).
Could a hard reset help (as for the old Touch Diamond)? I would like to avoid that due to the destruction of the data...
I have also posted this in another Thread but I guess I was on a wrong one...
Thanks in advance for your help and best regards,
B.

Did you try Google Maps with "Use GPS" function... Default settings find satellites, even indoor areas..

Yes I did. It worked after switching it off an on again. Now I got GPS with google maps. First goal is achieved. Thanks for this tip.
But: Does anyone know how to retrieve the configuration of my internal GPS device. I have to configure it in another application (odgps), but I don't get it to work (com4/4800 or com4/9600 or com3/4800 and some other config data is all wrong): Odgps gets no signal.
Thanks for tips and hints.

hi,
Same problem as Brummerowski here.
my TD2 shows my location on google maps.
but when ever i try to seek a GPS Satellite on google maps or Garmin it keeps on searching without a result.
thanks for your assistance

This same problem keeps on cropping up with the TD2. Some users never seem to have problems, others do (I'm one of those) and there have been countless suggestions to (try to) sort it out.
On my TD2, Google Maps won't start the GPS module any more (it used to) and I use another very simple app http://freewareppc.com/travel/wmminigps.shtml to start it manually before using Google Maps. This seems reliable so far.

Gps setting for google maps with d2
I was able to use GPS with Google maps, by setting gps options by choosing COM4 and baud rate from 4800 to 57600.

I have never been able to fix on any satellites using google maps, and been waiting up to 10 minutes to just find two or three sats.
Solved by running third-party gps apps, like Beelinegps, or GPS Config. For some reason they are able to get a fix in under 30 seconds indoors. Then I just switch to google maps and it shows my position instantly.

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.

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)!
