I have searched the interweb thingy for a fault similar to yours, but can’t find anything that might help you. Perhaps another member in here that has the same head unit as you might be able to shed some light on the subject. Maybe a full factory reset? I don’t know how to do that on your system.
I did read that some information from your unit is stored in the cars bsi. Maybe a bsi reset will clear the issue?
If you want to do a bsi reset yourself, here is the procedure :-
Put the driver’s window down, lift the bonnet and ensure all
equipment is switched off.
Ensure all doors are closed and remove key from the
ignition.
Wait for 3 minutes, disconnect the vehicle battery and wait
15 seconds.
Reconnect the vehicle battery, wait a further 10 seconds (do
not open doors.)
Switch on the side lights through the driver's window.
Switch on the ignition and check system’s functionality.
Hold lock button on key down for 10 seconds.
remove key open & close door test central locking system
Start the engine and complete the system’s check.
Failure to follow this procedure could result in incorrect operation of many
BSI related items.
lets hope this does the trick. If it does please let us know so it might help others in the future.
