i fitted an interface and camera in my e90 335d 2007
it was from this seller, i think it was this model (but check with him 1st)
he did me a bit of a deal as i got the camera at the same time (which was about £27 i think)
v good seller and was very helpful with any wiring problems i had
cam went faulty after about 6 months but he replaced it straight away and no probs since.
not to hard to fit, just time consuming taking trim apart. nice job for a warm, dry weekend
can play dvds etc as well if i plug in dvd player.
btw, it uses idrive screen as the monitor
