After recently recovering my Beomaster 5/Beosound 5 back to day one settings I am having an issue where it wont allow me to change the role setting from N Music to CD - allowing me to control the system quickly with a Beo4 remote. When I select CD the system always reverts back to N Music. It will however allow me to change the role of N Radio to Radio. Has anyone else encountered this problem and know a solution?
