What is the best possible way to bypass the D3 and still be able to mute the unit from a third-party device???
I have a Lincoln Aviator and I want to hook the real mute wire to my backup sensor so that when I am close to backing into something it mutes the radio and beeps...
But, I still want to move the mute wire so that I can perform the bypass...
Any suggestions on how to accomplish both???
Thanks,
Mark
