My Cd player has just died on me. At first I thought there was a CD stiuck in it but I have removed the unit and taken all CD's out. It goes through the motions of attempting to play a track despite there is no CD in the player. It then goes to a CD Error message. I can not load any disc's into it either. Does anyone know the best/cheapest place to buy a replacement head unit. It is for a 02 S60 and is a HU 803 4 disc changer unit.
