Hi, I have a Mercedes CLS 320 Diesel 2005. The Satnav dvd player is in the boot. I can't tell from the disk. Is my disk an NTG1 or a DX as I need to get an updated disk? Thanks
Welcome to the forum. evdok's answered your question already, but this is a useful list of part numbers to ensure you get the right DVD. I got a genuine v10 cheap off a German guy on eBay: beware people selling cheap illegal copies, though.
Incidentally, your car is a 3.0 litre, not a 3.2. The OM648 3.2 litre in-line 6 was never put in the CLS; you have the newer OM642 3.0 litre V6 instead.
