I have downloaded the 4.0 update. Now I get a Weak GPS signal alert after it searches for roughly 10 minutes.
I have tried all Com0-9 ports, hard resets, and uninstalling/reinstalling Google Maps 4.0
I have the US Cellular HTC Touch Pro 2, WM 6.5 pro, running the standard ROM.
Is this a HTC hardware issue, Google Maps issue, or USCC tower issues??
I had no problem finding 8 - 10 satellites with the old version.
Using my Tilt2 with stock ROM, Google Maps 4.0 got a fix for me.
GPS is a piece of garbage for this phone, at least for me,
It just never worked again for me since the stock rom (always says seeking satellites 0)
Alos,
"My location" is always is in the same spot (I can be miles away and says i'm in the same place)
I haven't done any research on this two issues, maybe some has my problems too?
Well maybe you should try this.
After I flash a new rom to get gps to work I have to do this.
Run "htcGPStool"
Leave phone outside for about 3-5mins until it gets a lock. After that my gps locks in 30seconds or less
ps, the baud rate for the tilt 2 is 57600- com 4
try the link in my signature for the aGPS cab.
This enables aGPS and changes the servers from the public ones which are configured on HTC (and many other devices) by default to the nokia ones which are maintained better and lead to a faster lock.
After installing the cab, run and update/download QuickGPS and make sure you have a data connection enabled then either try google again or htcGPStool or any other gps utility and see how fast you get a lock then
initial lock might take up to a minute, but locks after that come almost instantly.

Why does one need a data connection for GPS? OK, for Google Maps, yes, but just getting a fix doesn't require one -- or does your CAB do something that /does/ require a data connection?
A while ago I read people enabling bluetooth to get GPS working. Yesterday I disabled the cellular phone and it looked like GPS was locking after this. Not a fix if you ask me anyways...

you need a data connection for aGPS. GPS itself does not need one, but the a in aGPS stands for assisted where it uses your data connection to connect to a server to locate you more precisely.
(My understanding of this is that basically your device sends info to the server about which cell site towers are near you, the server uses this info to tell your device which satellites are best for your location, so your device isn't just looking for every sat. its looking for specific ones.)
Here's the wiki for aGPS
http://en.wikipedia.org/wiki/Assisted_GPS
Theres also a bunch of websites with more info regarding aGPS but its best to have your data connection enabled if you want to use aGPS.

Is "htcGPStool" QuickGPS on the programs list?? If not, explain thank you. As for the baud rate, etc... are you talking about the GPS hardware port? My settings say (none) and Baud rate: 4800???? This I have never messed with, could this be the problem??
ATT Tilt 2 w/ stock ROM...Loaded google 4.0 today with no connectivity issues. I normally able to locked my GPS signal in seconds.....

No, "HTC gps tool" is not the same as QuickGPS and it doesn't do the same thing.
AFAIK, QuickGPS talks to a server and gets info on where/what satellites should be visible for your location, your location determined from triangulation (or some kind of location) of nearby cell towers.
HTCGPStool uses the GPS functionality of your phone in some way that helps subsequent lock on satellites. Honestly, I don't know exactly what/how it does -- but it's not the same as Quick GPS.

Ok, where is htcGPStool??? Looked through the settings and have not found anything that directs me to HTC gps tool.
I have an "external GPS" icon that directs me to GPS settings allowing me to change GPS program ports, and the GPS hardware ports.

QuickGPS downloads the ephemeris data so that it can predict where the satelites are, which ones are visible, and which ones to use. From that data it is able to get a fix faster. There is no fix derived from ephemeris data, and any GPS will work without it. The GPS device in that case must basically just scan channels and listen for enough data to get a fix.
That all said; no problems here with Google Maps.. If I'm inside I'll often get a location approximation based on cell ID's and whatever goes on behind that location calculation and depending upon how the building is constructed I may or may not get a GPS signal eventually. For example my house, no problem, I might see the approximate location for 10s then the real GPS location. At work with heavy beamed roofs and several layers of metal between me and the sky I'll never get a signal inside except beside a window. If I'm outside, I nearly immediately get a GPS fix.
http://www.how-gps-works.com/glossary/ephemeris-data.shtml
As far as I know HTC GPS Tool does nothing except allow you to basically reset the GPS, ie: perform a warm or cold restart on it. Perhaps this will help, vs rebooting the phone, if GPS is not behaving. I very rarely will find the GPS is simply not functioning after a reboot.
This tool also might let you change the COM and BAUD but you would not likely need to do that on a phone with a built-in GPS. Even if you were using an external bluetooth GPS I'm not sure you'd want to change the COM/BAUD here, you'd simply use the COM port you set up with that bluetooth device.
That all said, the only time I don't get an immediate GPS fix in Google Maps is if I'm indoors. If I'm in a light structure, like my house, I'll get a cellular approximation for 10-20s. If I'm at work with many beams and much metal above me I'll never get a fix inside.
Let me try to be more specific.
1. When utilizing the app, it locates me within 3100 meters. (pressing the blue button, lower right hand corner)
2. After about 10 minutes of the upper right hand corner stating "seeking GPS satellites (0)" the screen gives me a Weak GPS signal message.
3. I have tried changing com 0-9 ports, with no luck.
4. GPS is enabled
5. I have hard reset the device and reloaded all my working apps.
6. I have uninstalled/reinstalled Google Maps 4.0
7. I have tried different locations throughout Northeast, WISCONSIN.
8. I have tried it while utilizing WIFI. No luck
9. I have tried the Bluetooth remedy. No luck
10. Waiting on replies from HTC, USCC, and GOOGLE.
11. XDA so far is the only place with anybody responding.
HTC Weather TAB
Just got done talking to a USCC tech rep.
He has stated that he is unable to give any technical help with the Google Map app. (no kidding sherlock) He was not even of any help when it comes to the GPS settings, but he did state I am the second person that he has talked to with the same problem.
Now to see how quickly HTC, or Google responds.
The only worry I have is not knowing if it is a hardware issue that should be corrected by HTC. I noticed the HTC WEATHER tab works fine. is this using the same GPS settings as the Google Map app??
also, I have been holding out on the aGPS cab posted earlier. If, and when, I use this fix I will post the results.

HTC GPS Tool is not a standard app. Some cooks include it in their custom roms. I don't have a link for it handy, but if you search on the forum boards for "HTC GPS Tool" you'll find it.
That said, I don't know how important it is anyway...
ok, talked to an HTC tech. We checked the settings and these where adjusted. Still nothing. Got rid of Google Maps and tryd BING, and still nothing. HTC TF3D Weather tab seemed to update just fine, this gave the tech a reason to dump me on MSN and Google. Do you really think BING and GOOGLE share some programming similiarities????
Did you run Quick gps? That did it for me when I first got my phone.
It is installed under the programs lists.

I think they both access GPS via WM. Maybe HTC Sense (Weather tab) directly access the GPS?
I switched back to an older version which also did not work.
I tried a bunch of different settings and did get it working then today I keep getting a device.exe error and the GPS does not work at all.
Yes I have:
My Location set (not 911 online).
Windows is managing my GPS
Google Maps does not work
Bing Map does not work
IN Advanced Config I have Enabled and Disabled Assisted GPS
I am on verizon.
I searched and came up short on answers. Has anyone had this issue? Is there a fix? What Else can I look for?
TIA,
Dan

On my TP2 the settings are COM4 and 38400 baud. Try those - set it from inside the program - each application typically has a "Manual" setting for the GPS.
use the new bing maps...it's far superior...
Try using Visual GPSce to see if your GPS is working properly.
http://www.visualgps.net/VisualGPSce/default.htm
After installing, go to "Connect" and change the settings to COM4 and 4800 baud.
This is a simple program that shows whether you are picking up the GPS satellites or not, and will often work when other programs (like Google Maps) time out. If you are outside, you should start picking up the satellites within seconds. The bars will start to fill up (meaning the signal from the satellites is being received), and the indicator at the bottom right will turn green when you have a good enough lock for an accurate location.

I disagree, in my opinion the traffic provided by Google is much better. It also includes incidents and construction, and is easier to see at a glance how much congestion is visible.
Bing is prettier, but not more efficient. In my opinion, of course.

So your sis using 4800? Mine is always at 38400...

Its listed as 4800 baud for the Rhodium countless times on these forums, and elsewhere.
I also don't think it matter that much. On the newest Energy ROMs, the HTC GPS tool is defaulted to 57600 for some reason, and the tool started picking up satellites just fine.
Thanks Guys! I went back to an older google maps and reset all of the settings and finally did get it working.
I have looked around the threads, and have not found a similar posting. Please no flames if this is a dupe!
I am having a bizarre conundrum on Froyo with the Moto Defy and the stock camera app.
I have not used the phone with 2.1 and so do not know if this is an issue on 2.1
THE ISSUE: Latitude is being recorded into the EXIF data as a negative number. This means 3rd party apps interpret the location as being off the coast of Chile.
So why is this an issue? I AM IN NEW YORK CITY.
Additionally, despite my best efforts to fix this, when the Auto Location Tag function starts up it says "Retrieving City Name" and always returns with "null, New York" as my location.
This occurs with or without GPS enabled, and with or without a satellite lock. It even happens with A-GPS enabled.
Google Maps, and other apps, are able to correctly figure out my position -- even with just WiFi enabled.
Has anyone else encountered this issue?
Update
I'm curious to know the interplay between gps.conf and gpsconfig.xml
I tinkered with both, and now I have a faster lock on GPS satellites.
However, the BlurCamera.apk app still inverts the latitude to a negative number in the EXIF data it writes.
Anyone have any ideas?

I see, I'm not the only one with this problem. I made a similar thread (http://forum.xda-developers.com/showthread.php?p=11769279#post11769279) because i found this one just today, but what i want to know: did you fix this problem?
edit: lol. nevermind, didn't notice that it was you answering in my thread. but still no fix, damn
See other thread. (short answer: no.)
When my phone boots, the GPS begins 'searching' for a lock, which, when indoors, it will never find. I'm trying to determine what process or application is activating the GPS.
Couple of notes:
- The hardware toggle for the GPS is 'on' and I'd like to keep it that way; but I only want the GPS to activate when I need it (e.g., Google Maps, etc.)
- Using AutoStarts I've reviewed the list of applications that startup during boot, and cannot identify a culprit.
To be clear - I'm NOT looking per se for a list of apps that MIGHT be activating the GPS; what I'm looking for is a definitive way of determining WHICH specific app or process has activated the GPS. I do have a couple of logging/monitoring apps which I could use, but it would be helpful to know exactly what I'm looking for.
Thanks in advance!
I use google latitude and that's the only time I experience this. Whenever I'm logged out of it I don't experience the GPS at start up. Just my two cents on it. Might be the culprit for you too..
Sent from my SPH-D710 using xda app-developers app
<Bumping> this question back up, as I still cannot identify the process that's activating my GPS. Cheers!
Having the same problem on a Defy + after an update
Should the GPS be connected one time after the update?
I've run a gps test soft found on the market, connect the gps to satllites. close the soft. close the phone.
When ligthe the phone, ther's no gps icon trying to connect nor gps ticked in preferences.
Problem solved
Hope it will work with your phone to
