Here we have a good used navigation system antenna control unit, part number 997.647.124.00 removed from a 2006 Porsche 997 with only 54,000 miles. This should be the same for all 05-08 cars with similar options. But please verify the part number to ensure that it is compatible with your car BEFORE purchasing. May require dealer programming. You will get exactly the same items as shown in the pictures. Any question please just inquire.
