Hi Steve, you sound frustrated, I'm sorry to hear you're having so many problems with it! It sounds to me like it's not very well built, and you should ask them to exchange it for a different model. Here are a couple of things I will caution you with before you send it to Pioneer.
1. Don't just send it to them, they will likely lose it. Contact them first and get an RA number so they can put you in the computer and know what to do with the unit. That is done online, click here.
2. It sounds like you've done everything you can do, including the reset, firmware update, and inserting the disc. There is no more that can be done on your end, you were thorough.
3. Crutchfield accepts returns. I would first try to contact them to see if you can send it back for a full refund, and pick out a different model. They have a 60 day no questions asked return policy, if you still have the original box and packaging. Click here to get the return started, or call 1.***-***-****. They also need a RA number for processing.
Again I'm sorry you're going through this hassle, thank you for the detailed information. If you're having trouble with it now, they will likely test it on the bench and send it back to you with the note "nothing wrong". That's the reality of it. Be sure to try Crutchfield first, that is your best bet to avoid a total loss.
