If BMW control or data worked on your CHIGEE Display and then stopped, note what changed and which functions still work. Use the guide for the affected function and your connection method.

For BMW control, use the Wonder Wheel troubleshooting guide. For missing vehicle readings, use BMW data troubleshooting.

For Wonder Wheel control on the CHIGEE Display, open Settings > Peripheral > RC. Choose Nav for supported native cradle control or CGRC for a paired CGRC CAN or CGRC LIN.

The RC setting selects the control connection. Vehicle-data source settings are separate.

If the problem continues, contact us with your CHIGEE Display model and firmware, BMW model and year, connection method and previous test results. Tell us when the problem began.

You do not need to repeat completed checks unless we explain what extra result is needed.
