CD upgrade for NAV system on 2001 S430
 

The maps in my NAV are getting old and roads are being changed. The dealer wants about $270 for the US set. Is there a cheaper source or is there someone in Maine who wants to sell me Texas?
Thanks

Anybody have a more recent year CD they could copy?

Sorry, my M-B doesn't even have nav in it. Next time I visit my folks, I'll see if they have anything newer -- though I think their more modern cars have gone to DVD-based nav, right?

I remember being absolutely outraged when BMW sent me quarterly mailers trying to sell me new nav disc sets. Perhaps I have been spoiled by Porsche, which distributes them to me every year or so at no cost whatsoever. They just show up in the mailbox. Finest car -- and car company -- in the world.

Cheers, John
