Working on my car today was refitting the interior trim, its like the rear door card, but on my P1. It wasnt fitting right so took it off completely and found three black boxes all on there own wiring loom and obviously added to the car. started to trace the wiring and found a trimble GPS device and a wire running outside the car to a thin black plastic square think its an aerial. The three boxes one has ericcson printed on it an aerial coming out off it and a sim card fitted in it, the second is quite heavy and only four wires think its a battery and the third has wires from everything think its a control unit. Now here is the problem what the hell is it? I've owned the car for a year but bought it from a dealer that new nothing about the car to the extent that they didn't know the HKS front mount was an add on.
I think it maybe a tracker device hopefully. does anyone recognise this set up please help and if someone does how do I reactivate it?
