How do you mean?

20 and 50 is usually used to refer to the standard radios, e.g. Audio 20 and Audio 50, with the COMAND system been the next step up.

The reason I'm wanting to know is that my unit has SAT NAV and I think the DVD is a bit old now. Looking at upgrades etc on ebay there are many different types and Im a bit confused as to how to match the DVD disk with my unit.

I think the SLK has the COMAND-APS (NTG1)

Wow ! - Talk about confusing, MB certainly didn't make it easy did they. Actualy, if an upgrade disk still only reads 5 digit postcodes then I'm going to stick with the Tomtom. I know it's messy but at least it's useable. The one in the car is pretty dire to be honest and certainly not very user friendly.
