Hello guys,
I am considering updating my VW RNS 510 sat nav. I have seen discs advertised for £25 ish that are supposed to be genuine VW parts. If VW update it with a genuine disc, what is the cost? I am not that au fait with sat nav discs, so what are your recommendations, real VW by VW, done by VW or a disc advertised as gen VW? Also how do I find out what version I have now?
