Customer Question

I have the AVH-P2400BT in my truck..I am having a couple of issues. The first is if you hook a phone up via bluetooth and play music you cant switch back to the radio without turning the truck off and back on. The other issue is after the volume gets past about 8 the sound cuts off and you have to cut the truck back off and on for it to start working again. Any ideas why this is acting this way?
