Sounds like a great idea. This will not limit where the unit can be installed in the car because will not depend on a power source. Lets face it all the OEM Gps products installed and aftermarket Gps tracking devices can all be found in certain areas of the car...and car theives know this. This new product will increase the potential install locations and give theives a headache. Lojack is still the way to go if you ever want to see your car again.
