GPS out of the country?

Hello!
I'm just back from a trip from london. I brought with me my P4000 thinking that I would be able to use it's great GPS abroad.
It never worked once.
I thought this thing had an aGPS chip, meaning it was a true GPS that could be assisted by cell towers to find a fix faster. So, my understanding was that it should have worked abroad, albeit slower to find a fix then here.
As soon as I got back home, it started working again.
Any ideas?
Mod Edit: Moved from Titan Upgrading
Thanks!

If you were roaming overseas, then you won't be inside Verizon's firewall, therefore you won't have connectivity to the PDE server. The standalone GPS should have still worked, though it probably would take a lot longer to fix due to the fact you moved a great deal since the last fix. Did you try to use QuickGPS to download the ephemeris data? That probably would have sped up your fix a little.

I'm using tomtom, so, I don't need access to verizon. Anyway, I'm with Telus.
I've let it stand by the window for hours and it never got a lock. I didn't try QuickGPS.
Should I have switched something in the registry to have it work in standalone mode instead of assisted?

Well, i'm living in Republic Of Moldova. WE have no aGPS here at all, but i still can use GPS function on Titan. I have to wait about 1-3 minutes for lock.
I have installed DCD 3.2.6 rom and 3.42.50 Radio. Use SeaSGEE to download ephemeris data and Navitel Navigator. But Tom Tom and any other programs work fine too.
PS Sorry for my English.

I recall having a similar discussion in an earlier thread.
See if any of this info helps:

If you do that right, i'm pretty sure it won't even attempt to connect to a PDE server (when u change GPSMode), so you should be able to get a *slightly* quicker lock, as it won't waste time looking for that server.
I do also suggest using some other tool like QuickGPS to retrieve the ephemeris data before trying to get a lock; it *should* speed it up, but I don't know how true that really holds.

Ok,
Thanks for all the infos. I'm going to Madrid next month, I'll try again there.

I was able to get GPS locks all over Europe no problem this past July.

Well it doesn't matter whether you have Verizon or Telus when it comes to aGPS. I was referring to aGPS. If you aren't inside your carriers internal network, then you won't access the PDE.
The GPS should still work regardless, just in standalone mode, which is why I asked if you tried QuickGPS to try and speed up the lock times.

I was under the impression that there is a registry setting for the global "zone" for our GPSr to look for and that it was set to US.
From the posts I reviewed few if any folks have been able to lock overseas unless they got locks while traveling
GC, have you found any settings in the registry for this?
In QuickGPS I think the setting is as follows:
[HKLM] - Software\HTC\QuickGPS\region
Its set for US for me here in TN and I think someone from Holland posted on PPCGeeks a long time ago NL worked for him to get a lock once he found and got it via trial and error...

I am sure you are onto something here
I think you guys are really onto something here. I have had the most frustrating time with my titan because of this very issue. I travel outside of the USA frequently and in all my travels have only managed to get a lock once! All through Australia and Thailand with no phone signal I was unable to get a lock with either flight mode on or phone mode on. Even in Taiwan where VZW has some modicum of representation (i.e the phone function worked but zero data) I go no lock.
gc was right about the agps thing. Outside of Verizon network you will not get assisted gps (although strangely when in "extended area" roaming inside USA it still seems to work).
in the end i tried a hundred things to get a lock including leaving the phone out in the full view of the sky for 6 hours. Nothing worked except the gps mode that scrawnyb talked about. I finally got a (very slow) lock after what seemed like hours.
I really believe that osteo's answer about the zone (i.e. "US" here in USA) is also part of the answer. I can only assume that the ephemeris data has to be relative to where you are on the earths surface, so the phone having some idea of where you are surely would help (especially without cell tower help from agps).
Targitai, if you visit this thread again can you please check the setting in your phone to see what zone setting you have that assists with locking. You need to look in [HKLM] - Software\HTC\QuickGPS\region and check that you are not set to "US" or similar.
I wont be traveling OS for a few months now, so I cannot confirm any of the above. I hope others who are traveling see this thread and can report back.
Thanks for the helpful info on this thread. This problem has been bugging me for months. Strange this is that my bluetooth gps never takes more than about 2-3 minutes to get a lock, even after crossing to the other side of the earth, over 9000 miles to Australia.

Well,
I'm here in Madrid now and it doesn'T work.
I tried changing the registry key of the GPS mode and it didn't help.
Any other things I can try?

How long did you wait, and do you have a clear view of the sky?
After traveling a long distance it can take some time to download the full catalog info on the satellites.

I waited a few hours in clear sight of the sky.
My old hp hw 6515 with a old stand-alone GPS chips can find a lock fine...

sorry, double post...

I have had my gps lock over the ocean in an airplane. I dont have navigation software installed other than google maps so I just used Visual GPS to verify I had lat/lon fix and a gps speedometer app to tell me I was going at the same speed the captain had said. No wireless data connection at all.

Hi, I have a similar problem, but when I'm in a no service area, the GPS locks in 2 minutes. When the phone gets a cell phone tower, never gets a lock unless I let him overnight catching sats. I'm from Venezuela, may be the cell phone towers or the network, I don't know, induce some kind of conflict in the position calculation of the GPS. In the flight mode the problem persist.

Verizon 6.1 MR1 Update with GPS fix - is it still working or has Verizon blocked it?

I'm running the stock Verizon 6.1 MR1 update with the GPS fix from here. The following GPS programs are loaded:
Fransons GPS Gate 2.6 - using the WM GPS setting to get Iguidance to work
IGuidance 4.0.2
Micosoft Live Search
Google Maps
Everything was working fine last night but this morning Live Search won't find any signals (even though I'm outside with a clear sky). Google Maps doesn't find any satellites. IGuidance satellite indicators aren't working and Franson shows a yellow icon saying "GPS data but no position" - Running OK!
Would someone please let me know if they have the MR1 update with the GPS fix from here and is getting Live Search information today. I'd like to see if Verizon has somehow "screwed" the data signal so this fix no longer works.
Thanks!

Did you try to do a soft reset on the phone? If they are blocking anything it would be the aGPS but not sure how they would single you out. Mine is still working and I am on DCD 3.2.6 with Radio ROM 3.42.50 and my GPS app is getting the aGPS info and then locking indoors.

i think that a soft reset is the GPS best friend
mine always works right off the soft reset

Yep - tried soft-resetting the phone about 7-8 times over various time of the day and still no dice.
I'm going to pair it up it back up with my I-Trek M5+ receiver when I get home and see if get locks on those programs.
Thanks!

just tried it here in NJ and it is working just fine

You might need to change the aGPS mode back to 2 in the registry. After upgrading to the latest PRI and all the GC aGPS stuff, I wasn't getting a fix in doors as I was. So some other post said that they changed that registry setting to 2 and that just worked for me.

GPS stopped working
Verizon must have figured out a way to block the aGPS. I have two XV6800's and both are out of commision. Worked last night, but not this "mourning". I even tried to install the "uninstall" cab by GC, but it would not install. Any ideas?

I have an xv6800 in NY and I just now got a GPS lock using Live Search inside my apartment. Seems to still be working here.

O.K. It's back up now. Verizon might have had an issue in certain areas today. I'm in Ohio and didn't have GPS all day. Now it is back up and running on both phones. Phew.

Sorry, didn't get a chance to post yesterday.
Mine came back up at about 2:15 pm yesterday in Northern Va and it's been fine since.
Probably some hiccup in the network or atmosphere conditions (sunspot activity etc).
Thanks for help everyone!

I had the same problem this weekend. My GPS (google maps) died on me. This was while travelling across Kentucky and Indiana. I tried a softreset a few times. Reinstalled Google Maps. Nothing. Monday, it started working again.

I'm beginning to think that Verizon has some issues with their aGPS servers. I'm constantly having issues here in central New York with not being able to get a gps lock.

Working great for me. I have yet to have a problem or not get connected within seconds.

how do you get the agps addresses and still have DCD roms? is there a seperate cap file for the Agps servers?

Google Maps 3G Issues

Has anyone else experienced a problem in Google Maps where the My Location feature will only work over EDGE connection. I have searched and read about this in a few other places but have found no answers. Im in NY and it was working fine just a few days ago.

yea ive noticed that to, it says location isnt available at this time or something like that but i can confirm that it works perfectly over gps option!!!

Actually today it started working again, good news i guess but i dont know how long it will last plus on 3G it gives my location within 1000m while edge did within ~300

GPS still doesn't work? Try this.

Greetings all!
Ever since updating from 2.1 to 2.2 my phone (i9000m) has not been able to acquire a GPS signal. I tried everything I could find on xda and online to no avail. While the 'Test GPS' application was able to identify satellites, none of my applications could (not even Google Maps!). Miraculously, I stumbled upon a solution earlier today. Once I turned off my Wifi (and I don't mean 'Use Wireless Networks'), my GPS started working instantly. The signal locked on FAST and was ACCURATE. I don't know why this happens. Maybe the Wifi interferes with the GPS? Anyways, I decided to share this right away in case it could help others with a similar situation.

P.S. My GPS settings are stock settings other than my Accuracy, which is set to 30m.

Is GPS working in non-US country?

Hi guys,
I purchased the DVP from States and using it in South Korea now.
Seems everything works fine except for GPS.
Does anyone have GPS problem? Any solutions ?

I use this phone in France and no problems with GPS!

Yes, it works both in China and Russia. You may need to wait a long time for the mobile to communicate with the satellite.

do you have the offline gps maps? The one I purchased has only online Bing .

works fine in UK

It works semi-fine in Canada for me. And by that, I mean it takes longer than what I have been used to with my android devices to pick up an accurate signal. Of course as everyone knows, my compass is dead as of Mango

Works in India too!

Yes - I've used mine in Spain, Canada, Scotland, England, Ireland, Italy, Portugal and the U.S.

Hi, my GPS on the DVP wont work, somebody have the same problem??? some issues to repair?!!
Thanks

try to use wifi when youre in maps and see if you get a rough general fix. if the circle doesnt shrink past 350m or something like that then youve got the common gps bug. its in more wp devices than just the dvp.. Lots of mango-ed devices report it.. Reverting back to premango fixes it. Or in lots of cases, it just fixes itself.. Mine did after a few restarts and a few days.
You can also download a gps testing app (e.g. gps test) off the marketplace to see if you get raw data from gps.. If not, highly likely the bug. wait it out a little?
