Sorry to bring up an old subject, but ....

I've had my car a year now and there are two things that are really annoying me that I haven't been able to fix; hopefully someone has had some experience which can help.

I have the factory fitted RCD510 and the dealer fitted Volkswagen reversing sensors installed.

The initial batch of 6R Polo's which had the RCD510 and reverse parking sensors fitted at the factory are able to display the sensors on the RCD510; also I was told that the dealer fitted Volkswagen sensors would disable when I was towing.

I would really appreciate it if someone could tell me if they have been able to get their RCD510 to display the sensors, or been able to get the sensors to disable when towing.

If not, it would be greatly appreciated if someone could explain to me why this isn't possible; as far as I am aware the dealer fits exactly the same parts as the factory, so surely it is just a setting somewhere in the computers? If it is a special part, does anyone know what it is so I can order it or them?
