Head unit didn't turn on

Kothar · 09-25-2017, 08:11 PM

Started car today...the nav radio head unit was black not on. Turned car on and off several times same thing. Car ran no issues. Went to work parked for day. turned on to leave 8hrs later and head unit back to normal. Anyone have this before? Loose connection?

Hmm weird...I've had the same thing happen but only with the sound, head unit was still on but no sounds whatsoever. Solution was the same as yours - waited a few hours at work and poof, works again.

any chance you left it parked in the hot sun? my bmw performance steering wheel used to overheat when i parked outside in the summer and wouldn't turn on till it cooled down a bit.

Was in garage all night when turned on in the AM. But was left out all day in hot sun when it came back on later that day after work!
