I had a similar one from Alpine, probably an earlier model, installed in my lambo 3 years ago after some fuckers crowbarred my radio one night that I had left the top off. (covered secure garage, didn't think thieves would get in).
The little control LCD display was mounted in the ashtray.
The radar sensor is really good. Can't put your hand in without it detecting it.
There is an inside radar, and outside radar.
That tended to really drain my battery though... but V12s and batteries are always a love-hate relationship.
