Hey, just after a little advice really. My 51' plate S3 has a Bose system in it. I've been quoted big-ish bucks to get a an aux port which requires me to have a phone kit, just for this privilege. Also it's started skipping CD's & I think it's approaching being knackered. My main question is, has anyone fitted an aftermarket head unit in? That incorporates well with the bose & preferably fits nice in the dash? Mine also has the 6 cd changer built in to the head unit if this makes a difference. Or is it too much hassle? Cheers!
