Did this just start happening or did you just install the radio? Chances are you have some wiring problem (well not 'chances' there is a problem with wiring). Check all the power & grounds to the radio and changer, make sure they're clean and if necessary take them off the light circuit.
oh! now that you mention it, i think the changer is hooked up to the accessory wire. need to change it to the regular power wire..... thanks
