I have had trouble with the Co-Pilot Live GPS program on my VTAB the last few days. When i put in the address to navigate to and push "GO," the VTAB re-boots. Very frustrating. Together with the lack of support for ad hoc networks, bluetooth keyboards and Apps to SD, I 'm considering returning it to Sam's. Battery life seems to be decreasing with every re-charge as well. Anyone else have this problem?
