I believe VW and Honda use the same navigation system “I think?” I know Volvo and Acura do. Anyway I have an 04 VW Touareg and had to order a new set of Nav CD’s. These CD’s were not available at the dealership and I had to buy them directly from the manufacture of the NAV system at a cost of $195.00 not including shipping. You might be able to find them out there somewhere else but not sure how up to date they will be. I would just call the dealership and ask them where to get them.Once I put in the new disk the system was busy for a while and a notice was shown on the display screen that it was updating the system including cleaning out the built in flash drive. It’s worked like a charm since then, although I think the system could be a bit easier to use. Anyway good luck!
