A question regarding the head unit in the R. I currently have the RCD 510 and am considering upgrading to the RNS 510 at some stage. Reading through the manual the RCD 510 is apparently security coded to the vehicle itself, so i'm guessing if i was to remove the unit but replace it back into my car at some stage it wouldn't require me to enter a security pin. However if i was to sell the RCD 510 a pin # would be required for it to work in another vehicle?

In other words should i of received the security pin # with my VW Manual or do you have to request the code from VW?
