For Garmin Zumo XT or XT2 Locking Adapter for BMW NAV GPS Mount "The adapter that makes it work" If you are upgrading your Garmin NAV V/VI to a Garmin Zumo XT or Zumo XT2 GPS, this locking adapter will allow you to mount and secure the Zumo XT/XT2 in the same location as your previous BMW Garmin NAV V/VI. You must have a BMW NAV base as shown in the images and a Garmin Zumo XT or XT2 to use this adapter. This adapter is designed specifically for this configuration and is intended for use with the Zumo XT or XT2 Nav base included with the purchase of the Zumo XT or XT2. This adapter is compatible with BMW 1200 GS/GSA and 1250 GS/GSA models. The adapter enables the Zumo XT or XT2 to be mounted securely into the BMW factory NAV base, restoring the original locking function and factory appearance. It eliminates the need for aftermarket handlebar mounts. The adapter kit includes a matching plug for the factory wiring harness located in the right frame area. You will need to connect the supplied plug to the Zumo XT or XT2 harness using the included crimp connectors. Once connected, the assembly can be plugged into the vehicle to provide power for charging and ignition control. When installed, the Zumo XT/XT2 extends only one additional inch toward the rider, maintaining full visibility of the instrument cluster.
