I drove to Canada from NC using the Navi on my F90BT. 5 miles from my destination the navigation begins to glitch ala max headroom. System now does a constant reboot from the Pioneer sign to black screen. Every 50-100th reboot, the main screen will come on and I can play music, however if I try to use navigation, it immediately goes into reboot mode. Any suggestions? I have a 12 hour drive soon, and would like to use my radio.
