Hi all, just to ask, I have a cd changer for the r171, just to ask does any one know if this is an easy install ? Is there the optical wire in the glove box for the changer to connect to ? I would rather do it myself than pay Â£180 + VAT (17.5%) not including parts [!] They say it will take 3 hours ??? What they planning to do spend 30 mins putting it in and 2 and a half listening to cds on it ?? Any ideas would be great.
