Hi I just installed a Pioneer AVH-P4300DVD with a metra dash kit in my 2010Camaro SS,the problem I have is the volume goes up when I stop at a light,and it goes down when I take off,could this be a problem with the GM speed sensitive volume control or could it be a control in the Pioneer unit that is causing this,should I go back and turn off the GM volume control??Thanks.

disable the option in the settings or check if you can reverse the polarity of the option..
