Audi A4 Sat Nav uprade for Le Mans?

[DiscountDave]

...i'm taking my '56 plate RS4 to Le Mans this year; can anyone help recommend what DVD upgrade to ask for and where best to get it from?

Trying to avoid getting fleeced at the approved dealers.

Cheers, D'Dave

...my God; they want £200 for it!
