So, I've got an interesting issue w/ 3.0. I accidentally left the map light on in the Outback and the car battery was fully drained. No worries, I jump it and drive around for 30 miles or so and all is well... Or so I thought.
I encountered the "blank screen, car thinks it's on backup camera" problem, the "hard buttons don't work but the touchscreen does problem" but both went away. Now I've got a new issue: the clock is getting set wrong for the AVIC software. If I go into Ezrider, the GPS has locked and iGo correctly displays the time as HH:MM PDT. But in the AVIC software (AV.EXE, specifically) the time is (HH+1):MM! I can usually correct this by going into Settings->Navi Settings->GPS and Time->Time, turn on autocorrection (which thanks to the usual time zone bug puts me into Idaho), turn off autocorrection and then back out. At that point the clock in AV.exe is updated to the correct HH:MM time. But if I power cycle the car, on the next boot the AV.exe clock is back to an hour ahead! At first I thought maybe it was a timezone change issue (the new rules added in '07 or '08) but the AVIC-F90BT on my desk is working just fine. Tried doing System Restore to reset to factory defaults and deleted user data, but still no joy.
Luckily I can just refer to the clock on the dash, but has anyone else run into this? So far the closest I've come in the Search was this post and this one but it neither had a solution, just a "fixes itself and then breaks again" at the end...
