Ok the mailman just arrived with the back-up cam. With a quick hookup and check, it works great. That is as long as the E-brake is up. Will be doing some more testing to see if disabling the E-brake will let it work in reverse?
If anyone has any Info on this please let me know. If all goes well I'll have a Bac-up cam for 40 bucks.
P.S. you still have to hit the Aux button, but hey for 40. bucks
