I have had my Droid x for almost two years, love it. I am an avid user of VZ Nav when I travel, especially at night. In August I noticed it would start to nav, then lose GPS. Went to a store, they had no solution, except to refund two months service fee and delete it from my phone. I waited a week, loaded it again, same problem, and got lost driving at night. I called tek support 3 days ago, they had me do a factory reset. Grrrr. I'm still having the same problem. I did ensure the compass was calibrated, although that wouldn't make any difference. The google navigator quite often shows my house in a different area, it seems sensitive, so I have to play with it. I really like my VZ Nav and want it to work. From talking to my tekkie friend, he said it is a VZ problem, and not the phone. So,in three cities, that are very large, I lose GPS according to VZ, however if I make a post to Facebook it can post my picture with a location tag that is correct.
I would appreciate any assistance that doesn't void my warranty.
Thanks!!!!!!
