If your CHIGEE Display’s wonderwheel controls or data reading were working properly but have suddenly become inconsistent or stopped, the issue might be caused by the following:
If you are using the CGRC CAN/LIN Module
Check whether the CGRC Module is working normally. The status light on the module should show a steady blue light during normal operation. Navigate to Settings > Features > RC, switch the RC Type to "CGRC"
If the blue light is not steady (e.g., flashing red or no light), there may be an issue with the module or the BMW’s power/data connection.
Also, check your BMW’s electrical system, including the ECU and battery, for any intermittent issues that could affect communication.
