Hello m8,
I do have a NEW CD changer for sale to fit your car.
I recently collected my new C200k from Belgium , but one month prior delivery,I purchased a cd changer + bracket+F.optic + harness for me to fit after taking collection.
But when I whent to collect the car in Belgium , to conpensate me for the delay of the delivery date, the dealer gave me an other complete cd changer.
In my way back in UK , I installed one of the changers my self with no problems.
So if you are interested I'm selling it inc. Fibre optic + bracket + harness for £300 inc. shipping.
I can even let you have the instrction to instal it or redirect you to a web site for you to download the instructions.
