The ground connection from the amp to the chassis is probably loose

Generally, I would say just set them to where they sound the best to you. Different people have different tastes and ideas as to what sounds the best.

bad audio ic , audio output ic

I had this exact same problem. Here is how I just figured out how to fix it. First of all, my friend as an iTouch as well, so I plugged his iTouch into my DEH-P4000UB, similar to your 3100UB, and it actually worked and played music. So I went to my Music then selected a song and pressed pause. I turned on the car and then plugged the USB cable into my iTouch, exactly the same as yours. When I replugged my iTouch into my deck it gave me a different error this time, Error-19. Refreshing but still frustrating. So I turned off the car, unplugged the USB cable and tried it one more time. This time I selected "Repeat" on the song, don't ask me why, but this is exactly what I just did. I turned on the car, plugged the USB and it worked!!!

I understand your frustration and I've been dealing with it for a while now. So hopefully this helps. Good Luck!

verify if your remote is working by seeing with your phone camera (infrared light) :)
