For specific BMW models (K1600 series and RT series), if you want to control the Chigee device using the original BMW Wonder Wheel, you MUST purchase the CGRC CAN module.
However, installing the CGRC CAN on these specific bikes results in a "Simultaneous Control" conflict. Because the bike’s internal protocol shares data channels, rotating the Wonder Wheel will control both the BMW dashboard and the Chigee device at the same time.
These limitations are inherent to the design of BMW motorcycles. Unfortunately, CHIGEE cannot offer a solution to resolve this issue.
