The IID tool is linked to one specific car, but I think Steve might do dealer ones, I have no idea if anyone here has one. You can get your own one for under £300 and it allows you to control many of the functions on your car, one of the best investments you will make.

As to the spoiler, I don't think it is easy to fit an aftermarket camera to the existing spoiler as there is not really space to do so, I bought a used one from the bay that came complete with the camera. They do come up at breakers etc. Other than that you may be able to wire something in above the number plate if it will link to the cable plugged into the head unit. Tom
