Q: What does code U0485 mean?

Invalid Data Received From Radio. U0485 is a network communication code indicating that a control module on the vehicle's data bus received invalid or corrupted data from the radio or infotainment head unit. The module that set the code detected that the radio's messages were missing expected parameters, contained out-of-range values, or failed a checksum, so it flagged the radio as sending invalid data rather than no data at all.
