Mib 1 on the
280 is a small screen so to go MIB2 with bigger screen you have to make space for all the new hardware.
I believe there is some cutting of the dashboard to get the 7" screen into the original
280 space.
When I spoke to the guys about buying one of these they wanted 1200 fully fitted including rear camera. Never went further as I decided on engine / suspension first this after. If you check out the Video it still shows the turn navigation in the centre screen but as I say I have not double checked the detail. Reason I liked them is they support all the car functions.
