2002 E320 Navigation System question

[CR2002E320]

I just purchased a 2002 E320 with the Command Navigation Systmen but no CDs. I only need a cd of the Pacific Northwest region which I believe is cd #2. How do I know what to specifically look for when trying to buy just that disc, e.g., model number, etc. so that I don't buy the wrong type?

Any M-B dealer should be able to figure that out, and there is MBUSA - you can call them at 800-FOR-MERCEDES, or write them at mbusa.com - there will be a "Contact Us" link on there. As a last resort, you might find info and the CD on eBay.

I bought disk number 7 release 7/2001 Part number Q646 0091 on Ebay for my 2002 E320 and it works fine.

Disk number 2 of this same release set would be part number Q646 0086
