Just thought I would share a bit on info here as I have a GPS Tracker on my boat so also put one on my A6 Quattro. Pretty cool device. Great covert type alarm as it is hidden and you can locate it 24/7. Sends text and emails right to you in seconds. Has lots of features as I see it is great on my boat as I have more concerns of it being stolen than my car but check it out....
