Update:
I do not recommend this head unit, and in fact Alpine's customer service can suck it too. I've had lots of problems with this head unit, between using USB storage for music and the 'random' not working properly, to channels intermittently working/not working (sometimes the front speakers drop, sometimes the left channel drops, sometimes the right channel drops, sometimes all 4 door speakers don't work, and there is no consistency or any way to duplicate it), and Android Auto has a mind of its own, which might not entirely or at all be Alpine's fault.
If a Moderator sees this post, can you copy/paste this to my OP? I'd really like to pass the buck for anyone to steer clear of this head unit/amplifier combo. It sucks to have to say it, since I've been using Alpine since the 90's.
