I HAVE A 2001 430s AND WANT TO UPGRADE THE COMAND NAVIGATION CD. I SEE THERE ARE A LOT FOR SALE ON EBAY. HOW CAN I FIND OUT WHICH CD WILL WORK IN MY CAR.

 

See the post at http://www.benzworld.org/forums/audi...ation-dvd.html for the release and part number of the January 2007 CD release. Not sure when the next one will be out - they're updated approximately annually.

Your dealer can give you the information on the latest release (in stock) and its part # - but you lkely won't find the latest of e-bay.

Your car has a "D" nav system. Do not buy discs for the "C" nav system, and don't buy any nav DVDs.
