Satnav

[Bretttf]

How can i tell what version my satnav is?
It's the DVD version on a new w212 E class.
It came loaded but I got given a new DVD that is still sealed in the case. Euro maps 2010-2011.
I daren't put the DVD in incase it doesn't work and I end up with nothing!!

It is probably a Navigation 50 which comes with a DVD based map. Comand uses a hard disk for mapping. Didn't the dealer give you a spec sheet with the car?
