Just installed Pioneer DEH-P80MP stereo, and on the display ATT is displayed, also audio is low and will not turn up. Is it because ATT is displayed? How do I remove ATT from display, so I may increase the volume?
Type of Electronic: Stereo System
I have not tried anything. I did not hook up the blue/white wire on radio harness because I did not know what it was for. Is this the problem?
Welcome to JustAnswer, my name is XXXXX XXXXX X'm here to help get your problem resolved. Yes this is because ATT is displayed which can be used to turn down volume to that level instantly at any time. On the remote you should have a button that says ATT to unmute it. Let me know if you have questions,l thanks.
