How can I tell whether my Navigation System uses a C-Navi, 11 CD set or a D-Navi, 10 CD set?
You can find out by looking at one of the CDs located in your Audi Navigation System. Printed under “NAVIGATION SYSTEM”, near the top of the C-Navi discs will be “for C-type navi systems only”. Also, the C Navi System has 11 CDs and the state of Hawaii is contained on disc 10. The D Navi System has 10 CDs and the state of Hawaii is contained on disc 1 with California and Nevada.
