Thanks. Just checked and does require RDS or RNS 510 large screen for DYNAUDIO. Probablly order cheaper RCD version and swap later for RNS 510.
That's what I did. Bought an RNS off eBay from a guy in Lithuania for £600. It took me 10 minutes to fit and worked perfectly. I then sold my TomTom (£100) and my RCD510 (£350), so the RNS only cost me £150.
It really is worth having and not only for the satnav. It has loads more features than the RCD, not least of which is the HD which has enabled me to put my entire music collection of some 2000 tracks on to it for instant access while driving
