Which GPS chip? - P3470 General

Hi all,
I am thinking about buying a used Pharos. I would like to know which GPS chip is built in - is it a SIRF III or something else like MTK or Venus?
Which experiences do you have regarding the sensitivity and the precision of the GPS? Is it comparable to a SIRFIII Bluetooth receiver?

hi
htc pharos am equipped with a head of gps inserted
configure gps external com4
maretiel com2 4800
and in software gps : gps inserted ou other MNA com4
see you ,

That does not answer my question: Which GPS chipset is built in?
Anyhow, next week I have my Pharos and can find out myself...

i thought it had a sirfstar III chip... but not sure

Best bluetooth gps receiver...

Hi guys!
I'm looking for a bluetooth gps receiver form my Jam with TomTom 5... any suggestion?
i just bought a holux-236 off e-bay @ £96 inc shipping. Haven't tried it out yet, but read a load of reviews prior to purchasing that sang it's praises. Apparently you can keep it in your glove box and it'll still pick up & stay fixed on sats!
i also have a Holux gpslim 236 this is a great receiver, it has a usb car charger so you can use it with the magician
GlobalSat BT-338 receiver is one of the best - Got mine on eBay for £60. Any receiver with a SiRFStar III chipset is good. Look at www.pocketgps.co.uk for reviews of receivers, there are newer SiRFstar III receivers than the BT-338 now which are more compact - that site will tell you all.
At ebay I bought a "Bluetooth Nemerix GPS Receiver, 16 Channels", wich came in a nameless package (I can't find any brand on it), and it only cost me €65 inc. shipping.
Only after 2 hours the bluetooth began to stop, and after half an hour it was completely dead. Do you might buy a good-one in stead of a cheap one
I wouldn't recommend the TomTom reciever. They make great software, but the reciever I got from them is tempremental, sometimes it establishes a fix in seconds, and sometimes it takes up to 20 mins.
hi.
i'm using RBT ROYALTEK 2001,
its working flawlessly , i'm getting fix in less then 2 seconds.
also SIRF III.

Elyl, I have the same GPS, it works great when it wants to. The problem i have with this gps is that it tends to lose its BT pairing on my MDA. Its looks ok from BT menu in win2003PE but TT5 does not see it. This means i have to delete the BT profile and recreate it Bit anoying.
Just wondered if you had the same problem or if anyone else does ?
PS/ this is my 1st post after reading the forums for a while and would like to say hi to one and all

At the moment I'm thinking to buy one of these for my Jam:
Royaltek RBT2001
Globalsat bt 338
Wich is the best?

I can't say I've encountered that problem. One thing to bear in mind, which is a fault of TT5 - when TT5 first starts up, and the BT GPS is on, TT5 will report "No GPS device present" until your GPS gets a lock. What it should really say is "No GPS signal".
As I remember, I thought it wasn't paired the first couple of times I used it, but if you actually wait a minute or so the GPS will get a fix, and TT5 will appear to "pair" with it.
So, more than likely the re-pairing you do is unnecessary, it's just that TT5 gives the wrong message when it doesn't have a signal. Another known problem with TT5 is that it will sometimes do a cold start on your GPS after a certain amount of time if it doesn't get a good enough signal... this is unnecessary also, and means it takes longer to get a fix. TT5 is far from perfect!

I use a normal Kirrio...it's all ok.
I see what your saying Elyl,
But after 30 minutes of waiting and resetting the GPS and reloading tomtom, then to delete and recreate the pair and it works within 1 minute makes me think my setup has a flaw somewhere. Will reinstall TT and the BT support.
Anyway back to the topic, the BT-338 is one of the best specced GPS receivers with SiRF 3 chipset for the price. The battery life is excellent too. Ebay is a good place to pick one up from but watch for the carriage !

Agree with this! I own BT-338 and it works very well with Magician. Recommended, very good receiver.

Never had any problem like this with my BT-338 + TT5 + Magician.
And I dont turn on the Bluetooth settings (you know, the blue icon in the bottom left corner). But the TT5 stills be able to pair it. Never lost the pairing.
Oh btw, I use ROM 1.01 The oldest one. I dont upgrade it because it works fine.

Has anyone seen or used the following gps receiver?
http://cgi.ebay.co.uk/SOLAR-BLUETOO...818331769QQcategoryZ69928QQrdZ1QQcmdZViewItem
Read the review of that solar GPS on http://www.pocketgps.co.uk - basically, the solar bit is just a gimmick, and not very well implemented. I think the review said something like you'd need to have it in direct sunlight for about 20 hours to get 1 hour of life out of it.

I think he needs the GPS software not the GPS receiver ...
OFF again: the holux 236 is quite a piece :wink:
I use TomTom 5.21 with an i-blue receiver. I am pretty happy with it here in South Florida, USA.

Haha, yeah, I just read his post more carefully this time. So I'll recommend again, TomTom Navigator 5.21 ! That's the best so far and pair it with SiRF Star III chipset Bluetooth GPS receiver
I use TomTom 5.21 in US and it's working great. Heard lots of good things about it for UK too. But I have no idea for China and HK.
I use Destinator PN. Very pleased
I heard TomTom is a way to go when it comes to maps (software) in US and Europe and possibly in China, what about hardware though?
Seidio RBT-2010 vs Holux GPSlim236 vs i-Blue ???
I am currently shopping for a GPS receiver as well, and globalsat BT-338 seems to be the one that's recommended 90% of the time. Anybody paired one of these with their Wizard?
GPS for the Qtek9100
I just got the Holux gr 236Slim yesterday and it just rocks.
Its very sensitive.¨
Getting about 10 satelites with the GPS from inside the compartment.

No antenna?
No antenna, just the HOLUX 236 :lol:
SiRF-III should be the First consideration
I am experimenting with a Globalsat BT-338 with my Wizard (Cingular 8125). I am extremely pleased with the ability of the GPSr to work inside the house, in closed stairwells in office buildings and in densely wooded area. I am having other problems related to my desire to use my investment in Garmin maps with this GPS, but that's another story....
One word of expectations: The user manual is nearly non-existant. Also, the GPS locked up on me once and the only way is to remove the batter (which is easy) and then put it back after a couple of hours. If you face any problem, the tech support and forum moderator at Globalsat sucks, but I will give them points for being prompt with a reply, however canned that maybe. Very cheap at US$130.
I'm using Fortuna Slim GPS
SiRF Star III
standard nokia battery
8+ hours autonomy
optional bundle with car power supply adapter
really fast
light
really good 2D accuracy and good 3D accuracy
marru
I am using iGuidance and an iBlue receiver with my 8125. I get 10 sats from the car and can usually get about 4 from inside my house, enough to get a fix but not really doing much navigation inside my home!
It has paired flawlessly with my device. Best part is that is goes into sleep mode and then wakes up only when the paired device requests data. So that means I can have BT on, on my 8125, use my bt headset and the unit stays in sleep mode. When I open iGuidance that wakes the gps and it gets a fix usually in about 50-120 secs. Most of the time by the time I am out of a parking lot or earlier.
So far the maps from iGuidance have been pretty good. The latest release on their website fixes a 3D display issue. Best part is installation is painless, no copying CAB files to get it installed. So far I only have PA, MD, and DE on it and that is about 115M. The longest run I have had with it has been 6 days of about 20 hours of on time and the rest of the time in sleep mode.
Another vote for TomTom...
The receiver they have is great, too.
TomTom 5.x and Holux 236Slim get my vote - Holux is very quick to get fix, even from inside my glove box - and it shares the same connection as my Wizard for the car charger, should it run out of battery.
I have the holux now and cant get it to pair with the 8125
I cant get it to pair with the 8125...new outgoing port does not show up..when i push new partnership it does not find anything. WHats wrong

Dopod 818 Pro and TomTom

I managed to successfully install TomTom on my Dopod 818 Pro, but TomTom is unable to locate a GPS. Is this someting I must buy separately? My really old Zack Morris Nokia had a built in GPS that connected to satellites okay. Doesn't the Dopod have GPS capability? Is it a config problem? Thanks for your advise.
No the 818 Pro does not have a built in GPS, you need to go and buy a Bluetooth (or cable) GPS separately.

No cable - it MUST be bluetooth.

Thanks a bunch. Now I am thinking of buying a GPS receiver with Sirf Star 3 chipset. Ones from ebay are: New Solar Bluetooth GPS Receiver 20 CH SiRF Star III 3, or Holux GR 236 Bluetooth GPS Receiver SiRF Star 3 III. Anyone have any problems with these in the past?
Hi,
I'm currently using the Holux receiver without any problems at all.
As far as I know, given most BT GPS receivers comply with NEMEA standards and Bluetooth SPP protocol, it is quite hard to find one that's not working with our devices.
I bought the Holux 236 because it uses the same mini USB connector as the Prophet to recharge the battery...
This way I have to take with me just one charger (or car charger) for both devices.
Bye!

Prophet + Holox BT-541

Hi!
My problem is that I have Qtek s200 and TT6 and I tried it with friends BT GPS reciver. It worked like charm. I was so thrilled so I bought one for myself at once. But I noticed that TT6 with my new Skytraq GPS wasn't so "quick" as it was with my friends gps. It was "late" 10-20 meters and updated very slowly when I was turning on the new road. With other gps (from my friend) it worked superb!
I did some research and only difference I could find is that my friends GPS is SirfIII and mine is Skytraq (Holox BT-541). I am satisfied with other aspects Mine BT-541 is much better than the other gps (friend): battery time, sensitivity (indoor receiving), Smart power management with Vibration sensor so I don't freely want to change gps reciver. A lot of people on other forums says that it can depend on bluetooth connection.
Is there any help? Tweak?
I don't want to buy another one!
Thanks in advance!
Greetings from Sweden
Well I've got a cheap Holux too (rebranded as "nothing at all"...). With a WM5 Prophet (Qtek s200)
I bought it as a proof of concept, to see if I could record mountain bike tracks and for car navigation - I too bought a copy of TomTom6.
Mine too has a lag in terms of position, and also in terms of refresh (I can be coming off a roundabout, and the GPS display is still on the roundabout).
My plan is to buy a sirf III GPS, i'd prefer to borrow one for a couple of days, but I don't have that option...
I think a sirf III receiver will resolve your problems (& mine)
Hi Paul!
Tnx for your answer.
As I mentioned with other gps (sirf III) it worked like charm.
I borrowed my friends gps last weekend just to double chek it once more.
And YES, it worked superb!
So yes, I think too sirf III gps will solve my/your problem.
This is mai I recived from Skytraq ([email protected]):
This the first occurrance we heard regarding slow response of BT-GPS using our chipset.
When the receiver seem slow while turning, is the environment much blocked having bad visibility of the sky? Or is it fair sky condition?
When doing a side-by-side comparison of SiRFstarIII and our GPS receiver, we see similar lag between the actual position and the displayed when driving with both receivers. This is due to reason that : GPS receiver takes a snapshop measurement of your actual position, do some calculation to get the lat/lon position (about 400 msec), sends it out through UART and Bluetooth interface using 38400 baud (also couple hundred millisecond), and the map takes a little time to decode and display dependent on CPU speed in Qtek s200. Thus there may be 1sec ~ 1.5sec lag between the position shown and your actual position. When driving fast, such lag will be more significant.
Best Regards,
i was using a bluetooth gps receiver i bought cheap on ebay, 1 of the older chipsets, but that wasn't good, anyway that went kaput & boght a holux 1 with sirf iii chip & all is good
so yeah maybe it is just the chipset of the gps & u noticed it your self
Interesting reply from the manufacturer, though... is he just trying to confuse us with technical talk? It seems the Sirf III has a faster reaction.
I've tried all sorts of tweaks (upping the baud rate for example), and still have that lag.
Later today I'll try with overclocking (just installed BatteryStatus ) and see if that reduces the lag.
However, our experience so far indicates the Sirf III chipset is simply faster.
I allready tried with overclocking!
Unfortunatly - that is not helping.
Still same lag!
I think I'm gonna sell my Prophet and bt gps and buy HTC TC instead buying a new gps device.
Have read some fine critics about gps in TC.
The only problem is that TC is not aviliable yet in Sweden
But so0n

Questions about GPS of HD2

Hi,
I'd like to know if the HTC HD2 supports the following when used as a GPS navigation device (using the right software of course):
1. EGNOS (WAAS in the US) - en.wikipedia.org/wiki/Egnos
2. Instant Fix II - sirf.com/products/location2_services.html
3. TMC - en.wikipedia.org/wiki/Traffic_Message_Channel
Thanks for any input!
Regards,
mrcool
as starters, the hd2 doesn't have a sirf chipset (I wish it had....), so it would be no to point 2)
there is no tmc device built-in
to the chip: my hd2 is faster and more accurate than my navigon 7210 with a sirf chip

second that
Thanks for the answers! I had no idea that Instant Fix II is exclusive to Sirf. Just used their website as a link because it was one of the first Google results!
Pity that TMC is not included...
Does anybody know about EGNOS/WAAS capabilities?
