Have just gone to JB HI-FI and coincidentally was looking at head units..

I came across the Sony XAV-622, Has anyone dealt with these badboys?

I'm looking at getting some form of head-unit installed into my 2002 mk4 golf preferably with dvd, aux - pretty much the whole meal-deal without satnav..

Can anybody help me out?

Will it fit for starters? maybe installation costs? maybe you know of a better head unit? or you do work at JB and can get me a discount? ha
