I'd be VERY surprised if that was the extent of it - at the very least, I would expect a firmware update to remap the buttons on the multi-function control panel ... buttons shown on p.4-2 have to behave like the ones depicted on p.4-3. Yes, there's a possibility that the wiring is all there and the head unit will just "detect" the cameras if they're plugged in, dynamically reconfiguring itself, but I doubt it.
One indicator might be whether your external mirrors have a plug where the camera is located on AVM-equipped models, or if completely different mirrors have to be purchased.
