Sorry to post in an old thread, but this is the first time I've seen the iPod/ iPhone CD Changer cable posted for use with the stock Head Units.
I have an RCD 500 in the car, seeing as the 6 CD Changer is built into the Head Unit, will this cable still work for me?
Also, how difficult is it the actually route the cable into the glovebox? Do you need to cut anything? Or just guide it through with a coat hanger as you mentioned above?
Thank you again for your help!
