Do all C55 with COMAND also have NAV? At MBUSA on the new c-class, they appear only as a combined option. I'm beginning to suspect that may not be the case on the C55. I'm hunting for a used C55 and wondering if I can tell which cars have NAV just from the pictures. I've searched the forum without luck.

Also, how many DVDs with NAV - just one?

Thanks

Yes. Comand = NAV. You can easily tell the Comand / NAV cars by no exposed slot for a CD or DVD. The face folds out and down to expose two slots - CD and DVD. Also the NAV screen is inset as opposed to flush.

The NAV just needs one DVD.

Thanks - I had the impression from something I'd read here that you could get Comand without Navigation in a C55.
