I have just bought the car above and it has the Bolero head unit, my parking sensors don't look anything like the screenshots I have seen, its more like a bunch of lines behind the car graphic in monochrome, and I don't know if they work, the documentation in the manual refers you to the Radio Manual, which refers you to the vehicle manual, so really useful, anyone tell me if there are any settings for this system? In fact tbh I found the manual confusing and contradictory throughout, on the upside at least a graphic appears when you put it in reverse, it just doesn't seen to react to anything, how close do objects have to be? When I pick the car up on Friday all may become clear or I may back into a low wall.....at least it has a towbar for protection lol.
