No. Installing the CGRC CAN or CGRC LIN module on your BMW motorcycle does not cause you to lose control of the BMW TFT.
Once the module is connected to your BMW interface, you can use the BMW WonderWheel to control both the CHIGEE Display and the BMW TFT system.
How It Works
You can switch control between the BMW TFT and the CHIGEE Display using the MENU button on the WonderWheel:
TFT Mode: Controls the BMW factory TFT system.
NAV Mode: Controls the CHIGEE Display.
This allows you to simultaneously operate both systems without losing any original BMW TFT functionality.
Please watch the instructional video provided below. The video will guide you through the steps to control the CHIGEE Display and TFT using the Wonder Wheel.
