The Axxera Radio adjustments are non functional when the turn signal/side cameras and the backup camera are on. Some find it irritating...we have not had a problem, in that the turn signal is on for a short period of time and same with the backup...we seldom find that we need to adjust the radio volume/station in that short period of time.
each of us has a personal preference and tolerance
