My Kufatec IMA rear view camera solution has worked very nice, but I wanted to test with the original camera since I was missing the trajectory lines what you get with the original module from Q5, Q7, A5, A6 ect... so I bought a R8 reversing camera module and installed in my A3 today 
Basically I've did the same connections as with the Kufatec solution, but instead of having a wire from RNS-E <-> Kufatec IMA for reversing signal, it has to go to the central electronic. You would also have to code the CAN Gateway to support reverse camera module.

Sorry for the quality of the images...
After starting the thread, I've remembered that we had a discussion here: http://audiforum.us/rns-e/9392-backup-camera-trajectory-lines.html
I've couldn't find a way to switch between parallel or perpendicular parking mode, but the default mode (as in the images) is way far the best! The mode can be changed through VAG-COM (bit 15 if I remembered correctly)
My module is 420 910 441, and physically I’ve placed it where the CD-Changer is normally placed – it doesn’t fit (because of different sizes, but with the help of some foam it seems to be okay…
Of course it’s a more expensive solution to do the original retrofit that with the Kufatec IMA solution, but it’s far nicer and much easier to park
