I upgraded from the RCD 510 to the RNS 510 and the 9W7 Bluetooth kit. Both of these were ordered off Ebay from the UK. All arrived in about 1 week in perfect condition.

I had my local VW dealer installed and code my car to use the parts and everything is working perfectly.

Voice Activation
Compass
Directions on the MFD
etc etc.

But that also means I now have a bearly used RCD 510 lying around... What are peoples thoughts on this? Is it worth keeping the original parts that came with the car? Or is there really no point?

I was looking at getting Extended Warranty on my car down the track, so does that void it?
