my original factory nav unit was perfectly fine! i wanted dvd, but did not want to add a interface module or place a dvd player in the glove box. so i searched the cl forums and found only 1 other person who did it. his diagrams were good, but i was still confused a bit with some gateway wires, so i studied it real good and ordered a j54 plug from dealer
and installed some wires into the new j54 plug and tapped them onto the J53 harness that was on the side of the old nav unit without cutting anything! this way i can just plug in the original factory nav unit if i ever want to go back. only issue i ran into was the airbag light, which i could not figure out how to get it to go away. i even called a guy in canada who has done it and still no luck, so i just removed the cluster and put something over the led housing where the light was. you could never tell i have a airbag light on at all, and it doesnt cause any issues except that if an accident happend the passenger airbag would not diploy.( i am not responsible if you do the same and air bag does not diploy in a accident, do at your own risk! )
