I bought a mk2 Focus a couple of weeks ago and noticed the radio had an aux button on it. After some Googling I found out the part I needed from Ford to hook up my iPod. I fitted it and it works great, the only problem is a buzzing noise when I try to charge my iPod at the same time as playing it through the stereo. I believe this is caused by a ground loop. Any ideas on how to sort it? If I take off the centre console trim can I re-route the grounding?
Thanks for any help.
