so you have an android auto head unit? do you have the android auto app on your phone? and just to be clear after pairing your phone to the car stereo head unit, you are now having issues with radio sound? i'm not sure what you mean by the scanner "labeled #5 on instructions" no longer works. so the number 5 button does not work? or the scanner does not work? what car stereo do you have? is it a factory unit from Jeep?
