You are not going to be able to get the stock changer to work with the Pioneer deck. They are not compatible.

on your wiring harness behind the stereo, you should have 2 blue wires. one solid, and a second blue wire with a white line on it. the one with the white line is your remote turn on. the other one is for a power antenna, and wont work to keep your amp on.

I would check both of the power wires for the unit. There is a yellow one and a red one. The yellow one always has power regardless of the position of the ignition switch. The red one only gets power when the ignition switch is in the on position. Also does this only happen when the vehicle is in motion or does it happen just sitting and listening to the stereo? It also could possibly be the ground wire not getting a good connection. Make sure the ground wire is tightly connected to something that is metal. Good luck.
