Should be this one. Correct?

The number you want is in the format BQ 6 xx xxxx

Then you can order it from an online Mercedes dealer and save some dollars.

(Don't enter the B when entering part number.)

Yes, that's the corrrect NAVTEQ catalog number for your car's year/model and COMAND unit.

The BQ 6-46-xxxx numbers (without the B) are Mercedes part number listings and specify which head unit. Here are the numbers and their corresponding head unit: http://parts-planet.us/products.html...n=4944&maker=7

But not many online Mercedes parts websites will list them. Just email/call with your model/year and ask for a discount. Or just get it from NAVTEQ. In the end, the prices are very similar from all the dealers and OEM suppliers. Check eBay, too.

FWIW, my M-B nav disc is North America 2010; #BQ6460257; Navteq #S0028-0070-909; and it's for MY03-08 E Sedans + other models.

220S

That's the right one, although he's looking for V.10, the very latest one. Your disk is the previous one.
