What does this fault code mean?
The digital radio receiver (RDAR) has been loaded with software that does not suit this car. The receiver may then lack data about how the car is configured, or it may not match the software stored in it. The code is stored once this is detected, and the digital radio then has no function.
Possible causes
- The receiver has software that is not correct for the car
What you can do
- 1Read the fault code, clear it and test drive the car to see whether it returns
- 2Tell the workshop whether the digital radio receiver is new, used or moved from another car, since that can explain the fault
- 3Have a workshop load new software into the digital radio receiver and check that it matches the car's equipment
Symptoms you may notice1
- The digital radio has no function
