Hi

I've picked up a second-hand RNS-510 version B unit and am ready for a DIY installation in a MkV R32.

I have the security code and GPS antenna (which I assume I just tape to some spot inside the dash?).

However, I'm unsure of what I need to do to have the unit "coded" to the R32 stereo components? I understand I can take it to the dealer and part with $600 - which is not really an attractive option. But who else has VAG-COM? Would they have it at other servicing mechanics? Please help.
