My 2008lx has a strange issue. Every once in a while I'll be driving along and the radio just turns off and the screen flashes an "audio off" message (I think thats what it says). Then I'll turn it back on and a little while later it turns off again. This continues for a while and then once I turn the car off it's normal next time I drive it (usually). Anyone had this issue? Maybe a loose wire or something?
