Have had the car for 10 years and unit has always started in an AM radio  pre selected screen. Car was recently driven by someone else and since then at sart up is in Media select mode screen  How do i get it back the AM radio presets scteen have always had until now?

Just switch to AM radio and then switch the ignition off

Just realised that actual issue seems to be that when bluetooth connection to a phone is established that is when the screen switches from Radio to Media. I don't normally drive the car, her indoors has been complaining of the issue last few days and I just noticed that this is the actual problem.
