Can anyone tell me if the MMI system needs the navigation unit installed to work? I recently purchased a 2005 A6 salvage vehicle that was hit in the front. The MMI system is not working and don't know if the unit was damaged in the accident or the fact that someone cut the nav unit and sat reciever out of the trunk while it sat in the salvage yard.

No, the nav unit need not be present (many other markets in the rest of the world don't have satnav). Maybe the MMI control box inside the glovebox is damaged.

was the optic lines cut?

Yes, the optic lines were cut. I assume that one was input and the other output. How would that effect the main unit?

okay...so what else exactly is supposed to be in the left trunk compartment besides the amp and k-box?? There is an amp located on the top of the rack, the k-box in the next opening, and the third and fourth spots are empty. There is also a small box mounted to the underside of the rack as well. I checked the units behind the glovebox...all are undamaged, however I suppose they could still be damaged from the impact.

If it has no nav unit, then the amp & k-box is all there is. Has this car got Bose? If it has then the small box is the aux amp.
