Hi all, i just joined the forums today and have introduced myself already.
Just to get the ball rolling with the questions.

I have a mk 4 Golf with a Eurovox 4680 head unit, now forgive me becuase i am a total begginer but what can i change that out with? I would like to change it with say RCD 300, 310, 500 or 510 as i really like there look. Otherwise what do i generally need to know, as in what type i should buy if these are out of the question.

Thanks in advance Milo
