I bought my ///M with jammers on and BMW had no problem transferring the motorplan...not sure thou who the installer was for the previous owner.
I was pulled over by the cops in a roadblock for having the jammers...not a nice experience, after that I was paranoid about every cop I saw on the road to the extent I wanted to remove to jammers eventually I blocked the jammers and disconnected the control unit.
