You should be able to reboot just the audio system, which you do by pressing and holding the audio power button for about ten seconds until you get the reboot message. This will work even when the screen is blank and unresponsive. And you can do it while driving also.Hi All,
Periodically, about once everyone month or so, the power for my radio etc. does not work. Restarting the car fixes the problem. Has anyone else experienced this?
