This
model is the only portable magnetic mount unit with a car power
adapter. This patent-pending system is the only portable kangaroo
whistle on the market that you can install in seconds rather than hours.
To Install simply set the magnetic mounted device on the hood or top of
the vehicle, open the door and run the cable inside the vehicle.
Plug the device in the cigar lighter for power in high rish areas and
open roads.
