sat nav disc

Anyone knows where to obtain a sat nav disc for a command system fit in the SL350 of 2003. I would be interested in an original disc, or better so, in a latest compatible updated one. I am both Norwich and London based. Many thanks

Hello! I’ve recently purchased a 2009 E350, with sat nav, the only issue is that the maps are out of date! What is the best route to take with regards updating? There seem to be numerous sites called “latestsatnav.co.uk” and “satnavstore.com” but are they trustworthy? Kind regards Stuart

Hello people I have Mercedes E250 coupe 13 which I bought recently.. it came with a build in sat nav (hence there is a sat nav botton) However when I try to go on the sat a msg pops up saying no sat nav module is connect... what does this mean and what am I supposed to do ? Thank you
