Garmin XT 5.0.20w loosing GPS fix and more....

OK Guys I was searching this forum and not only this but could not find any answer or tip to my problem, so as far as i do not like to start new thread here we go....
It is a bit weird as it started to happen recently...my Garmin XT working ideally with TOPO maps when u hiking but as soon as i get into a car and connect my HD to power and try to navigate home it starts to loosing the plot... basically it will find the route and start navigating and then suddenly loosing GPS fix and switch screen off sometimes, and even once or twice unload itself so phone went back to main screen. also once it lost fix i can see that Garmin switching between full screen and full window view...as i can see top bar every now and then.
contacting Garmin is a waste of time....as they did not offer any solution except hard resetting the device, and i wont do that, to much work to put back everything together and not enough time.
if anyone have a clue what it might be please share ur thought, and give me a tip to sort this out.
I'm using non modified HD with standard WWE version on Orange UK.
Thanks for any help
PS. For MOD, do not know if I posted in right place so if need to be moved, just move it.

Oh and I thought my Garmin was going crazy ! Actually Sygic is working fine with me except that I get some lags sometimes but it is all fine. But yeah tell me about it ... I tried Garmin and it looked for me better with much more POIS than Sygic but few days ago I was driving and suddenly the software started to go into other direction, like it was tracking something else. I think it is a bug with the software maybe. Thank God I am not the only one aware of many things going on with my HD

have u ppl tried 1.13.25.24 radio rom??
with this update... getting fix is very fast (basically it does not search for com ports, shows u connected when u start GMXT).
only drawback is that u can not see the satellite bars in info section.
used gps for short distances (@ 140kmph not much lagging and no disconnection). maybe i'll go for a long drive this weekend... then i'll know if there is a problem of disconnection or lagging etc.

With TomTom i get the same problem, however i don't know what the problem may be because A-GPS is turned off, but it has happened twice where it would take 4 times as longer to find the signal, and whenever it did it would go find then lost.
Soft Resetting fixed it up however i did notice my QuickGPS was not up to date anymore, must have went out of date the day before and possible cause for it acting up.
Try updating QuickGPS, might fix it up and be sure to have A-GPS off.

still no solution

i did forgot to mention that my A-GPS is already switched off. the problem is that Garmin keep switching between full screen and full window view and i suspect that my be the bottom of losing fix in the car... i want to stress out that while walking & hiking i have no such problem..... ONLY IN THE CAR and that is most frustrating.
and changing radio....well i'm not convinced as this could halt my phone if something go wrong and i cannot let it happen, as it's not only a toy but business tool, so i rather dont play with it.
any solution????

Changing radio won't halt your device. As long as you have Hardspl on your phone beforehand you'll be fine!

And pelase report back if it does solve your problem

Is this a solution????
Hi there, I see we lost some posts over here....so again latest update...
On the way to work this morning I tried garmin with Intermediate Driver and it worked!! but....there always has to be some but....I saw increase in lag...also i did it a bit different way then usually as I did not connected HD to power... will test it again with power connection tomorrow.

i have extensively tested gps of touch hd while driving from 0 to 120 km in open highway
i never lost the fix
it kept locked to satelites but major problem was battery drain
so i have to disconnect gps latter on
i belive with gps on and satelite fixed driving around 80 to 100 km battery with die with in 2 hours .
otherwise there is lag of 5 to 7 km/hr in speed calculated via gps and its normal
my SiRF III CHIP based cowon q5 gps also shows 5 to 10 km /hr differance from actual speed of car
its normal i belive

laggy but working

from what i experienced earlier with garmin i can say that lag become much bigger...now when i'm past the junction, on the map i suppose to be either on or even before the junction... never had that before so i suspect that intermediate driver might be responsible for that. also i can say that when using tomtom i have no such experience.
wanted to ditch tomtom but with such a laggy response i will have to use both... garmin for off road navigation and tomtom for car navigation.
the only thing i can confirm is that using intermediate driver solved switching between full screen and full window problem as well as loosing gps fix... at least for me. but u get bigger lag instead....

Weird GPS problem. Moving even while my car is motionless.

Hi i have weird problem with my GPS.
While I driving (car is moving) everything is beauty and sweet but once I stop my car my GPS is still moving for about 10 sometimes 20 sec showing 2km/h then 0km/h then 2km/h again. Sometimes when I stop car on junction my Gps will jump on the perpendicular road and from time to time my arrow on the map just turn around to opposite direction and the maps sets a new route! Once i move my car everything going back to normal.
I was using first my TomTom and i just thought it`s a map problem although i haven`t problem with that on my Rhodium either X1. So I decided to try Igo8 and it`s exactly this same. Even on the roundabout my gps can jump somewhere else on different road.
I tried all Radios available for HD2, many Roms and just have no idea what more I can do. Many people on HD2 forum in Poland have this same problem.
I also tried GPS fix cab downloaded here from xda but no luck its ever worst.
I can add that i'm getting GPS fix in few second so its good the problem is just my gps is moving around.
PS. Very, very rarely have no problem with this jumpin gps around. But is like 1/30.

Do you have access to an external Bluetooth GPS receiver you can test out? That could eliminate or isolate some possibilities.

unfortunately i don`t. but on my Touch Pro 2 and Xperia never had this problem.

hi,
are you using the 'gpsmoddriver' software, that is floating around here in the forum?. its made for using the compass data when no gps fix is available. it causes such failures in igo and copilot on my hd2. after uninstalling it gps works much more percise to me, when im not moving.
regards mad

Happens with mine as well. I have replaced my HD2 and it seems that the 2nd unit acts the same. tried various ROMs/RADIOs (official/cooked) - nothing seemed to fix this.
It's quite funny though... most of the people rather paying attention to the fix time instead of the accuracy (which is quite bad imo) in addition to this weird phenomenon. I doubt that the AGPS is somehow related, but it will be nice to know how to disable this feature, and try to acquire the signal without it. maybe this is the cause.

As i said before : i was using it. I had feelings its jumping around the places more than without it so I uninstalled it.

Tried to email HTC regarding this. they claim that their HD2's don't exhibit this behavior, even though I've tried two different units, from different batches.
I don't know what to do... this drives IGO nuts - it causes igo to switch lanes, directions and having the route recalculated without any good reason.

Sometimes its just pointless to talk with those dickheads.
They ll never say true.
With pink camera was this same. They were saying at the beginning that they have no problem with pink spot at all. And what was next? We need just more people to email or ring them.
Most of them even not using HD2. They've seen for few minutes and think they'll know everything about it.
It was so many bugs with this device they just dont want to hear about another one!

In addition to that, both of my units tended to show different position and altitude readings each time i powered up igo or google maps. while exhibiting the differences I obviously didn't from my current position, not even an inch.
to try to make things clearer. that's what I did :
loading igo -> acquiring signal within seconds -> getting a certain position reading with altitude of 11 meters (for example) -> quit -> reloading igo -> acquiring signal within seconds -> slightly different position, altitude of 75 meters or a negative value (for example).
even the small blinking dot in igo (which determines the actual gps mark) doesn't fit to my physical location on the road which I'm currently driving on. it sometimes blinks few meters to the right/left, and sometimes it tracks behind the guidance arrow (as it should be).

Could be
Simply a limitation of GPS. I have seen it on other GPS's. Garmin etrex. Try walking with one and even thou you are walking in a straight line it plots a zigzag path. More satelites (10+) should reduce this issue.
Basically the GPS is only accurate to a certain range from +-50m to +- 2 meters depending on the no of sats. The location is detemined by timing from when the signal was sent to when it was received. Calcs how far away the sat is (Speed of light??). It is possible you care getting a fluctuation in your current location. Eg
Sample 1 says you are point a.
Sample 2 says you are 2 meters to the right.
Sample 3 says you are 2 meters to the left.
Still in the +- 5 meters but the gps is plotting you moving backwards and forwards.

Guys, it is a problem everyone has, gps position is not as accurate or stable on the hd2 as on most other htc devices. And with an erratic gps position automatically comes an erratic speed. Don't know yet if it is because of a different gps module that's inside the hd2 or because of the inclusion of crappy gps drivers. Will try to find out soon....
Anyway, gpsmoddriver is not the cause of this problem since the problem is also on an hd2 without having gpsmoddriver installed. Because of the functionality of gpsmoddriver to improve the gps readings, in some cases it can amplify your erratic gps position, and that is also what some of you have been experiencing. Remember you can always use gpsmoddriver to add the hardware compass functionality to your navigation software, while additionally configuring gpsmoddriver to leave gps data untouched so it won't make the erratic position and speed worse. For more info or help, please visit the gpsmoddriver thread: http://forum.xda-developers.com/showthread.php?t=571266
EDIT: Of course the HD2 has a new snapdragon chip which has built-in GPS just like many previous generations of phones. Most likely qualcomm changed the way gps works in their new line of Snapdragon processors...

The movement of vehicles around you or even the movement of the sun's rays on buildings nearby can distort GPS signals. The GPS navigator software tries to rationalize this distortion and that usually appears as a movement when you are still. On the other hand, if you drive into a tunnel using TomTom and some other software, you will often see yourself driving straight on in the tunnel well after the GPS is receiving no more satellite signals.
In top-of-the-line built-in navigation systems, the GPS data is supplemented by inertial guidance. (Someone could create a similar supplement for the HD2 The supplementary information allows the system to reconcile the GPS information with information on your car's actual movement.
But for us mere mortals, we just have to live with it.

Well... this particular gps chip is quite useless, then. if my navigation program has to recalculate the route each time I stop at traffic light, then it seems that I either have to purchase a usb-based gps to pair with the HD2, or replace this device. I counted on it to perform well.

Complain to HTC, perhaps if they get enough complains they will come out with a hotfix or a rom upgrade that fixes it. Nobody said that the hardware is not that good (though it's possible), but it could also very well be a bad implementation by HTC!!

Already did.
They have obviously denied my complaints.
thanks again, anyway.

I noticed this behaviour yesterday night, at about 10pm. I was playing with NoniGPSplot, and while I was completely still (and freezing me arse outside believe me), it was tracking a movement back and fro and all around in small step, keeping track of me traveling some meters still while I was standing in the same point.
It was night and I was in my big yard, so no sunrays nor moving vehicles around nor buildings over my head.
I think this behaviour is very well hidden in tomtom since it automatically puts you on a road, and "smoothens" the gps data by making you follow that road no matter what, but a "realtime" software like nonigps tracks that all so well. Gonna notify htc about it now.

Guys, let's not go overboard on this. Non-military GPS is only claimed accurate to around 20 metres, regardless of the quality of the receiver. It's the US Defense Department messing with your HD2, not HTC.

Yes, absolutely, I've noticed the same behaviour with all three of the BlueTooth GPS I used in the past. So, I would not be too quick to blame HTC for this.

my touch cruise's gps receiver worked with static navigation enabled to avoid this false movement. maybe this is just a usual behaviour?

Agree to that.
But regardless of the fact that the thing is not a military GPS system, It should do it's work correctly as for me the GPS is almost useless when driving slow or within a city. My 2nd phone (HTC DIAMOND) and 3 personal navigation devices are mounted in my car to compare and all work fine when the HD2 isn’t .
The GPS looses all the time the fix to the satellites and then quickly gets the fix back. when using a GPS monitor you can see that the satellites constantly moving really rapidly. (moving --> getting fix and loosing it again)
This is for 4 other reference devices which are running simultaneously not the case so it seems really an issue with the GPS device.
I tested this with different ROMs (1.44 Vodafone, 0.6 dutty WM 6.5.5, 1.66 stock and another one I cannot recall the producer anymore.)

Hmm, I did try and track myself on the bus this morning and it did seem to have a problem finding me - it kept flipping between near where I was and about halfway back home. Used it walking down the street and again it didn't seem to be very good at nailing where I was (HD2 seemed much better). I've enabled location via cell location as well as GPS, so I'll see if that makes much difference.

This doesn't sound too promising :/
I've been using my iPhone 3G to track my runs when I head out, and I assumed the Galaxy would do just as good (or better!) at it. Hopefully it's something they can fix with a software patch and not a hardware problem...

Did you get it from Expansys? I am trying to find out whether it is just a batch or it is a more generic issue.

I too am seeing poor performance with the GPS. Seems to be a hardware issue.
I did a test over the weekend comparing my Galaxy S with a friend's HTC Desire. Using one of the many GPS utilities the Desire was consistently seeing and locking more satellites when stood in an open area outside. When running Google maps and showing the current location I found that the "accuracy circle" (for want of a better description) was growing and shrinking several times a minute causing the map to zoom in and out.
I've also noticed that the compass is almost unusable and showing a much lower signal compared to the Desire. I did perform the figure of 8 calibration several times.

Nope, got mine from Handtec. Really hope it's just a software issue that can be easily solved! Also noticed that google homepage in browser keeps saying I'm in China?!

Think I've read somewhere that samsung galaxy (the first one + the spica) have a broken gps driver causing such issues...don't remember if it was in sportypal forums or for a similar application. Very sorry to hear it's not fixed.

Nope I tried out google navigation at the weekend and was really impressed by the accuracy, it made my old tom tom look really bad.

So can we say that GS favours google navigation?
Can anyone confirm that?

This is very worrying, GPS is important for me, I don't want to have another N97 on my hands... fingers crossed it's a software issue....

I've not noticed any problems in Google Navigation. It found me almost instantly, and was so accurate in terms of showing me where I was while driving that there was almost no perceivable lag.
Whatever people are seeing it very unlikely to be a hardware issue, most phones use GPS chips from only 1 or 2 suppliers, its much more likely something temporary like a driver issue.

Yep, Maps works fine, including latitude. Also used Waze which took a little while to get a fix, but was also ok.

Well the journey home was much better! Probably helped that I was sitting by the window on the top deck of the bus, but I managed to get a much better fix, using both google maps and navigation. It wasn't like 100% accurate or anything, but certainly no worse than my hd2. Hardly got the large blue circle, but it did think I was in a field a few times, but that's to be expected. To note, didn't seem to make much difference whether I had both gps and cell data selected, or just gps.

My gps works perfect. Google maps finds it instantly and waze and speedometer apps work fine too. Localization is spot on. The gps even connects when I'm inside the house wich my Diamond never did.

I tested Navigon, which can be download from Market for a tryal period of 30 days now, and it working great on my Samsung i9000

it may be a firmware issue , everyone who is having problems should post the sw. version for comparision with others

Comparison of Galaxy GPS and iPhone 3G gps.
Hey everyone,
There's been some discussion regarding the "quality" of the GPS function in the Galaxy S, and after testing it out today, I sure hope it's a software bug or I'm going to be very disappointed.
This is my run as recorded by my iPhone 3G (with Fitnio): http://dl.dropbox.com/u/810054/samsung_fail/Picture%203.png
Now this is the same run as recorded by my Galaxy S (with RunKeeper): http://dl.dropbox.com/u/810054/samsung_fail/Picture%202.png
Take a wild guess which one actually reflects reality. Can anyone shed light on if the new "leaked" firmware fixes these problems?

They're all based on standard chipsets so its unlikely there's anything wrong with the GPS receiver itself. I hope it gets updated soon as it seems to be affecting a fair number of people.

GPS Troubleshooting & Solutions

Hi all,
I am new to the android OS, got my galaxy s a week ago.
I still keep my HD2 and to be honest I may sell the galaxy due to the poor gps reception and keep the hd2 for the next year.
The other thing I do not like is the fact that I cannot program the buttons behaviour.
Any way my question is, is it possible to disable the build in gps and use an external Bluetooth GPS Receiver?
The gps on my hd2 is miles, miles better.

I dont think its possible in this version of android. There is no way to tell the app to use the external gps instead of the internal one.
All we can hope for is a fix from Samsung.

GPS won't start
Hello, I am experiencing an issue with my phone and I was wondering if anyone knows a solution.
Basically the GPS receiver won't turn on when an application requests it, so it won't get any location information (the gps notification icon doesn't appear at all). This is definitely a software issue, because if you go to the settings menu and keep fiddling with the location settings (gps on<->off, wireless on<->off) at some point it WILL turn on and work correctly (and the gps icon appears), but randomly afterwards it will go back to not starting up again and you have to go back to the settings menu.
Is there a workaround for this? I'm hoping that a firmware update will fix it, but in the meantime is there anything that can be done? (I'd prefer to wait for the official firmware before flashing it).

Not really a fix but Extended Controls can make a switch on your home screen that will flip the gps function on and off, that will save some time if you have to go into that menu a lot.

I can confirm the same issue, rumour is that the upcoming firmware is going to improve the GPS a lot.

You can also use the 'Power Control' Widget that comes with the device.
Here you can turn On/Off a number of items, one being GPS.

I had this issue but it's just a case of going into settings and toggling the gps off and on again.

Good to know about the GPS on/off switch.
I was always rebooting my phone to get the GPS back to work.

There is an option in the secret GPS menu where you can set it to cold start, instead of hot start. Fixed it for me.

Bluetooth External GPS
Hey guys. I wanted to know if we can 'natively' from within Android 2.1 / Samsung Galaxy S use an external bluetooth gps...
In the bluetooth menu I can conenct to the TomTom bluetooth gps module but it can't be paired...
however after some digging I found this app:
http://www.androlib.com/android.application.googoo-android-btgps-AtDE.aspx
It does what it says. I get satellites straight away.
Now one big big problem with this app is that it closes as soon as I try and open another app by pressing the home button or even holding down the home button to switch between apps...
when the app closes it ends the connection between the TomTom bluetooth gps module meaning by the time a satnav app has opened the message box pops up and says 'do you want to enable gps'
why does this app close when you try open another app? No other apps like Asphalt etc close like this...
is there a way to use the external gps?
many thanks

From my limited understanding, no it's not possible. I don't know why, but Android has been a bit slow on the uptake for Bluetooth.
It's taken to FroYo to actually get Bluetooth Hands Free dialling - we'll see how good Google is in interpreting what you say to it, so far, it hasn't been successful for me on the phone itself let alone Bluetooth.
With regards Bluetooth GPS, I understand that it isn't possible. There would at least have to be some kind of underlying interface to overrule the internal GPS and feed the Bluetooth GPS information into the OS in place.
I want it to be possible, then we wouldn't care so much about broken GPS's.

Another GPS fix
Hey guy give this a try and let me know if it works for you.
http://theandroidrevolution.blogspot.com/2010/07/android-tips-tricks-samsung-galaxy-s.html

working like a charm, faster fix and i can actually use the GPS while driving (EU)

Isn't this like turng skyhook on?
Ie ,..whilst locki it uses wifi to identify where u are?

this fix it seems very accurate in Maps, whereas all other "fixes" did not work for me.
i don't notice anything different in GPS tester (i still hardly get any satellites if any) but in Maps my position seems to be very accurate....i'm just inside in my flat, but all other fixes never helped me before even in this situation.

Hello
Thanks for your suggestion for a GPS fix
Immediate I can not see the big difference in standard configuration and the change which you refer to.
I still have a unsettled GPS fix when I use Google maps.
However, I think I can see a slight improvement in the Google navigation. Now I remain almost always in the correct lane.
I use (default) I9000XXJF3
I've read that a newer version should resolve the GPS "problem", but is it possible to change the parameters of GPS I9000XXJF3 match the parameters of the new versions. ?
And just one question more.
If I close the GPS from the phone to calculate my position after mobile mast or WIFI.
How do I get it to find my location by WIFI.?
Hope for a response.
Thanks
Herman

This fix gives an instant , i mean instant gps fix with a clear sky.
on gps test gets 8-9 satellite now , when previously i could max get 1-2, that too not connect.
thanks a ton for this.
outside this fix i also had operation mode as ms based and had skyhook on.

I found this suggested fix a few hours back as well and have been trying it out.
I didn't get much better results from it to start out with but having played the accuracy setting I've found putting this up to 150 seems to make a big difference. Once I made this change GPS Test seems to show that the Galaxy is a bit less picky about the signal strength it needs before making a lock.
I've not gone any further in testing accuracy numbers beyond 5, 20 (the default I believe) 50 and 150. It might be worth trying other values.

S10+ GPS continuity problem [Stuttering location]

Hi all,
After a lot of testing trying to find an answer I come here for help.
My GPS is not working properly in an unlocked new Exynos S10+.
Problem: When you are in a car or even running, the current location "jumps" every 2 seconds to the new location as opposed to what it should do, move smoothly and transition following you. In the car it is quite annoying. It is like updates rate is 0.5Hz as opposed to whatever times per second it should do.
Facts:
It happens with all the applications. Google maps, Maps.ME, GPS diagnostics tool,...
It happens with google location services ("High accuracy") ON or OFF.
It happens at any location and always.
I have tried everything I could imagine except totally resetting the phone.
Can anyone try if google maps its updating the location smoothly with a decent level of zoom?
Any ideas how to fix it? It is the only thing that does not allow me to enjoy the phone fully.
Thanks!

are you running power saving mode or running the app in game tools? or running some performance tuner tools

No extra tool and it is running in optimized mode.
Is yours smooth when using google maps? Is the position updating continuously and not "jumping"?
Thanks!

Can anyone confirm if the movement of the GPS position is continuous and smooth or it jumps in discreet intervals? (Zooming it is more visible)
Thanks!

Has anyone found a fix for this? It got worse after the update to android 10 and it has made google maps basically useless. Thanks!

On my s10+ it is continuous and not jerky. I did however see on my car radio that is a android radio that the gps is jerky as mentioned by you. I have tried everything on the radio, but nothing helps...The only thing that i did pick up with the jerky movement is that if I have a destination/route in mpas, then it's smooth...if I just drive and maps is open, then it's jerky...I can't really give advice as it runs smooth on my phone.

Hello, have you found any solution? I have the same problem.
Will it be a software problem? Should I ask for a refund? haha
