Hey, so I've got a 55 plate MK5 Golf GTTDi with an RCD300 fitted, as standard they don't come with an aux function. However I've read on here you can buy a cable and plug it into the CD exchanger port on the back and may/may not have to get the CD Changer function (Press CD button twice) Activated by VCDS or some sorts. So I bought the cable - I bought the cheapest one I could find, and it doesn't come with the earthing point most do - which may be the reason it's not working & got the CD changer function enabled by my local VW Dealer. The cable is fitted and when you press the CD button twice it just comes up with 'No CD Changer' or some sorts..
I'm guessing it's probably the crappy cable but I'm to cheap to buy a decent one if this one works and I'm just missing out on something.
Any help would be appreciated,
Cheers!
