Has anyone else had this issue? My wife and I were out today for a drive and I noticed the clock and factory nav were off. When I checked the GPS info, it reported four red bars for four GPS satellites in the display, but indicated 0 GPS satellites available. I've done a reset to factory settings, rebooted the system a couple of times, and still no luck. Both the clock and the factory nav are off because apparently, for whatever reason, the system isn't connecting to the satellites even though the display shows a decent signal for four satellites. I'm stumped, and since my software is modded, I'm concerned that if I bring it back to the dealer, they'll say it was because I modded the system. Any suggestions?
