I have a faulty CD changer in my glove box - the screen display just says 'initialising..." The CD unit has power, but cannot eject the changer cartridge or play any CD's. I suspect the unit is broken and will need replacing.

Can anyone suggest any ideas and most affordable option to source a CD changer and confirm if a code is needed if the unit is replaced and where would I obtain the code from?

Many thanks for your help in advance!
