GPS Lag?

[BenC]

It's lock time and that is definitely not a problem with my device. I normally use the standalone mode and in it or the AGPS mode the lag is still there. As for the Quick thing, not a factor with lag.

Wow, what a letdown. Coming from an ATT TP1, I was looking so much forward for the lag to be fixed in the TP2. This morning on my way to work I tried out iGo, TomTom and Sprint Navigator and all of them had about 2 seconds of lag (Sprint Navigator actually was the worst with 3-4 sec lag). I don't want a Blackberry nor an iPhone nor a Pre. I want a fully functional Windows Mobile device! I am so fed up. My ATT Tilt GPS was working flawlessly (that was 2 years ago). On XDA forums there is GPS fix cab but it not recommended for CDMA devices.

The Touch Pro and Diamond most definitely do have a 2 sec lag.

Oddly enough, my Mogul didn't.

Wonder why that is, and why HTC didn't keep the same GPS chipset (assuming that that's the problem of course)?

First in Google Maps do you have the option checked to 'Use GPS'?

I had the same issues at first, then I followed the instructions and ran the apps as in this post -

Make sure you install the SDKcerts CAB first, then restart the phone. Then install Quick GPS. This will restart for you a second time now. Then connect to the internet via browser or whatever, then run QuickGPS and 'Download' the latest satellite info. When I didn't connect to the net first, QuickGPS failed to download the updates.

Now run Google Maps, should be almost instantaneous. If not, uncheck the Use GPS and then recheck it. My TomTom does like to take a bit to sync up, but when I go to the Settings>GPS Config area then it finds the satellites real quick.

These are instructions for unlocking Verizon's TP1 because Verizon had it locked down. Are you sure its safe for the TP2, or even necessary?

I had used TomTom on my mogul and touch with flawless precision and now with the TP2 it is completely unusable. I saw on XDA there was an improvement for GSM models, but so far no love for CDMA. Hopefully a fix or firmware update soon will help.

I could be wrong, but I thought QuickGPS was designed to help assist in satellite performance overall while operating by using cellular towers to assist, not just in initial lockdown.

Has anyone with the lag issues tried installing GFXBoost? Maybe the lag would be helped by the display refresh rate increase that this program provides. It could be a dispaly problem vs. a problem with the GPS.

I can not vouch for safeness or necessary but I will tell you it worked for me both times I tried it. Both times (starting from a fresh phone/hard reset) I encountered an issue, when I installed these in the right method it now works great. Slight delay like others are talking about here, but worlds better than before I applied.

I also install incorrectly my first attempt and I still couldn't get it working properly. When I reread everything, uninstalled and reinstalled suddenly everything was so much better...

Has anyone tested this on Sprint? I have about 3 seconds of lag and the blue dot keeps jerkin around. Not smooth and accurate like my Moto q9c was.

I think the issue lies solely in the GPS chip and its functionality (or lack thereof). I'm thinking that is the case because I've tried using TomTom and iGo with my Bluetooth GPS and the screen appears to run WAY smoother, presumably because the polling from the Bluetooth GPS is quicker and more accurate.

I think part of the confusion is that we don't know which carrier (Sprint, Verizon, etc.) model people are using. Each Touch Pro2 found on different carriers may be a bit unique, so that could be some of the issue.

Has anyone tried this GPS fix for TP1?
