Pioneer Z2
 

For the past week has been freezing on start up, had to shut off truck so could start working.
But today it didn't even start, but you could still see the start up letters. Any ideas?

i'd put a call or email into pioneer. if it's still under warranty they will replace or fix it, if not they might recommend an authorized repair shop.

When these units get to a certain temp, they tend to freeze up. Check out www.avic411.com. You might find an answer there. Good Luck. BTW, you know thw Z2 is bypassable now.

Yeah I've got the bypass, avic411 has no answer at this time.
