Thank you Shadow-Tech for this one. In the instructions when it says to run Wmodemdriverinstaller.exe is that to the XP Desktop or the mobile phone? It then goes on to say on #4 that On PC click start so was wondering about the instructions. I am thinking that this is on the Desktop Computer as on #6 it tells you to dial ##3424 then plug phone into USB cord. Hope this makes sence. I also did a reg edit a while back that helped the GPS when I edited GPSMode = 4 and went to 1 which helped my unit which is on Alltel. It does get a fix once in awhile but not every time I try. It sees satellites pretty fast but will not lock on until I hit the sleep button on top and then turn back on. I have noticed that sometime it doesn't work and the time will stop ticking on the GPSViewer program to prime the GPS. I will try your fix here and report back what I find. Thanks again.
