A 30-second check. Look at your BMW navigation cradle and answer two questions.
Older Navigator cradles carry four buttons on the front bezel, usually marked +/− or page/menu. These cradles cannot hold a CHIGEE display.
No cradle at all? Many BMW motorcycles leave the factory with the navigation wiring in place but no cradle fitted, because BMW sells the cradle separately. You do not need to buy the original part — see the option below.
