Hi, I am looking to sell my CLK 430 Convertible but until i have 30 posts i am unable too. However the CD mechanism on the Audio Unit has gone and it won't accept ro eject CDs and therefore the built in Sat Nav is unable to be used. As i dont want to spend on it unless i have to before i sell it does anyone know the cost of this in Paisley/Scotland area. So far i have seen a new audio unit, plus it would need to be coded by Mercedes then installed by someone, which i am led to believe is approx 1 hour labour cost for each job. Does anyone know of any cheaper ways?
