I just updated from R5 to R7 and I'm still having issues with the GPS. Specifically I'm using Google Maps/Navigate and they can't seem to find my location. The first day I flashed R5, it took a few minutes, but Navigate eventually locked on and started working. I just let it run for 45 minutes and it couldn't locate. Has anyone else has any trouble or success with GPS in the 1.6 ROMs?
