hey i know what you mean.you i put it in reverse its all crazy when it "Beeps/chirps".what i did was turn off the "Chime/beep"audio and just use the camera.so much better now.didnt like it when it was all stock to.i have the "Alpine.not bad but it just wouldnt play loud enough when i turn it up
Plus i had alot of audio stuff around in my garage(spkers/Amps/etc)i mean may as well put it to use.also what i found with that "AmpPro" switches in the back...they dont do "JackSchitz".dont know why there but for me....NOTHING(all this is just"MHO").the only thing the "AmpPro"do (IMHO)is simplify the installation between the "HeadUnit and Amp"
