I fitted a Kenwood DDX4025DAB, which was used from fleabay, super happy with it, Bluetooth, USB wired to the centre console cubby, and DAB is great in the car.
It is fully compatible with the sub and steering remote, providing you buy the correct plug and play lead(and turn remote `ON` on the head unit):- http://www.ebay.co.u...=STRK:MEBIDX:IT
