Its not the command option based on your info. It's a small gps console unit mounted high on the dash. It was installed at the dealership. It has the MB logo on it. I might be wrong but it may have a single cd drive for the gps mounted in the trunk just under the speakers. I'm purely guessing. There is a 6 disk changer in the trunk (lower left) for the audio. My problem is that I need to crack open the manuals on this sucker and learn a few things.... That being said, does anyone know how to update the maps on these gps units? I'll look around the forums too.
