B&O is on the list and much to my suprize not as difficult to fit as i thought it would be, seems the dash is the same and only a few mods needed to fit and the harness is very simmilar to the bose and could be adapted.. i missed out on a full B&O set up only a few weeks ago as there was a full speaker set up for sale for £360 complete but as i could not get the door cards i thought it may be too difficult so i am exploring another option at the moment
