L M A O!!!!!
double din as already said!
not sure about the direct replacement mate, the unit will fit in, it will save you on doing the single to double din conversion so the rns-e will slip straight in HOWEVER
im no expert on rns-e's if the loom is the same then yes (quadlock connector) it will work striaghtaway but will need some minor coding to be done via vagcom (not that important) if the loom is different in your car (i.e not a quadlock connector) then you would need to purchase one from kaufatec - someone correct me on the shop name!
and then its simply plug and play!
