I have a nissan x-trail t31 2011 tekna with Bose sat nav, single cd player. Now my problem is that the cd player has stopped to work. I am able to see the meny for the cd player but it doesnt respond when I´m trying to load a CD. Also the Bluetooth audio screen has disappeared. Sometimes the unit makes three beeps and then the bluetooth function suddenly starts to work. But when the ignition has been switched off and on nothing of it works. I think its a bit strange, I mean if there would have been a mechanical problem with the CD-player it should not have affected the bluetooth audio function. Everything else works like a dream, even the bluetooth handsfree. I have already checked the fuseboxes both inside the car and in the engine compartment, I have also disconnected the battery power for about an hour. Any ideas?

No ideas?
