Thanks aussietig for your guide - I recently installed a RVC into my MY12 Passat Wagon and used your guide to help program it up - the only issue was that the camera didn't work first few attempts. Then we realised that the can-bus gateway Module 19, bit 6C was already ticked which meant that the system was looking for the control module. It was a simple case of clicking this off and everything works perfectly!

A huge thanks for robinb for the vag-com help - a wonderful help!
