thanks to the help by magikmik I thought I'd make this to help others to bypass the Aux in Motion. Our MMCS uses the VSS wire (white with blue stripes) and the navi antenna to disable the Aux, while its in motion. I constantly use my iPod for music, so why not use the screen for something useful like a constant rear view.

First you'll need to splice your backup video input into an RCA cable and to your aux. I made a little drawing


I stole this image from mitsu forum - this will help as well


you will also need one of these for aux input and the PN#8750A145. I bought it from Mitsubishiparts - http://www.mitsubishiparts.net/catalog/?section=1020



Then you need to have have a switch to disable the Aux in motion. But first, find these wires here


once you find them get a DPDT switch - I also made another drawing


Here is the wire for backup video and my ipod for music

 

Mods u can delete this. I found the how to forum lol
