Lol, finally upgrading! Can't go wrong with a Pioneer tbh mate. You'll need the fascia adapter as the aftermarket units are smaller than those beastie standard one's, lol.
I'm after a Pioneer myself but not that one.
Ha yer mate, only had the car 3 years! lol.
The DEH-4400BT seems a half decent unit for the £ so thought i'd give it a go. Would love a double din unit but would rather spend the cash on cams and tuning bits
