I think it needs to go on Examiner, via a dealership.
It sounds like one of the RT3 settings has been changed from speaker output level to external amp output level and it needs changing back. Has it been into a garage recently?
no have only just got the disc from the garage and then found on start up the volume is very quite. if i wait for a command i can then turn it up but on restart it goes back to very quite
