philbeal Posted April 20, 2012 Report Share Posted April 20, 2012 How do you bypass the avh-p8400? I've tried the basic relay bypass and it doesn't work. Can anyone help?? Thanks. Quote Link to post Share on other sites

ForeverBronze Posted April 23, 2012 Report Share Posted April 23, 2012 Thanks, any specific programming instructions?? Thanks again for your help. It's greatly appreciated. If by programming you mean installation, just install it like the bypass before. See my post here for how I installed mine.. http://avic411.com/index.php?/topic/33388-avh-p8400bh/page__st__30 Quote Link to post Share on other sites

darkchild Posted August 29, 2012 Report Share Posted August 29, 2012 Hey i just bypassed my avh8400bh, but i am using toggle switch though!. it's pretty straight forward. I just used a piece of wire. one end is connected to the parking brake wire (green) and the other end to the ground. simple. flick the switch when you want to watch the videos and stuff. hope this helps Quote Link to post Share on other sites
