Today when I turned on my truck my battery was low. It was under 12v. So I unplugged my radar, turned off my nav unit by holding power button for 3 sec. I then turned truck on. The nav unit came on after turning on truck but then it went dark. The backup camera was not visible on display. When I press the power button it displays time on top right corner but goes dark after a couple of seconds.
I can insert a cd and eject it but it won't play. The radio, backup camera or nav unit doesn't work. If I press the media buttons or voice buttons on steering wheel I get no response. I tried turning truck off and on but no change. All I get is the time on the screen.

Any suggestions?

 

Disconnect the battery for 1/2 hour, and reconnect. It might be very very confused

 

Thanks, that did the trick. All working ok now.

 

Cool, thanks for reporting back
