vag-com experiments(help needed)

[jta430]

so i am hooking a rear view camera up to my rnse. i cant get it to autoswitch to the camera when i put it in reverse when its coded to an a4.
if i code it to a lambo or R8 then it will autoswitch to the camera.
anyone know of issues with lambo coding in a a4.
pretty sure both cars run on can-bus so dont think that will be an issue.
anyone who has vag-com and wants to try it for me (beers included)

thanks

You should check the telematics forums or pm avanttix on audizine, he did the reverse camera addition a while ago
