I have a Storm II and find that all of my tracking apps are grossly inaccurate. They are off 30 - 50% when I track distance. These apps include iMapMyRide, GPSed, and Ednomondo. I use these to track distances when I run and bike.

Google maps and VZ Navigator find my position accurately.

I am stumped. I made sure I was in open sky so plenty of satellites to hit. I can find no settings, location identifier, or calibration in the menus. No mention of this in forums.

I am bummed, I thought I was ready for the Iron Man.

Sounds like those inaccurate apps are using cell tower triangulation to find your position and not GPS.

Have you tried contacting the developers of those apps?

If these are working at least you know the device is working properly.

I have not. I figured since they were all off, it must be the phone's GPS.

These apps only use GPS, so it cannot be an issue with tracking via cell towers.

Thanks folks for the good ideas. Strange I am the only one with this problem.
