Ok..thanks to all you good people for the info. I've looked through the threads (using search feature) and the stickies. I've went to Crutchfield and nothing. Has anything been released (maybe Android - Phoenix?) to replace the head unit and keep all functions...including factory backup camera ? As mentioned in subject line..My radio says HD on the bottom left and 57032 on bottom right. Has screen with backup. I've read it should say JBL on bottom as well, but it doesn't. Vehicle appears to have 6 speakers. Any suggestions?
