Yes. The holder of the navigation preparation on the K 1600 GT / GTL is fully compatible with the Navigator IV and Navigator V.
As the Navigator V has a bigger display than the Navigator IV, the instrument cover on the K 1600 GT / GTL motorcycles before 2014 (part number: 46 63 8 546 302) must be replaced.
Only then does the entire screen of the Navigator V become visible. The matching cover for the navigation compartment can be obtained via the following part number: 46 63 8 546 367.
