Factory nav upgrade for 997.1 series AWD Porsches (i.e. 997 Carrera 4 series). For cars with PCM pre-installed (virtually all).
If your Carrera 4 came without nav, this is the complete factory kit that provides the upgrade. Sealed and new. Perfect.
Note: the kit for the C4 is different than for the C2. They cannot be intermixed.
Happy to provide details. In case there is any concern, I purchased this unit incorrectly thinking it was for a RWD (C2) car.

Best offer.
