Justin and others, that fixes the stealing of the vehicle BUT that is the best case scenario. Insurance covers most of that with 15-30% of cost of the add one unless specific lg insured.
The worst case is that they break in through the window and tear the electronics out. That is hard to clean and then insurance again. Hide radios, speakers, hams and CB'S so thirds don't see them. Out of sight means not to steal. Tuffy boxes are great so are custom speaker installs in the foot wells that use matching material so they are hidden more and try to use the stock head unit. A big screen custom unit is an invite to a thief.
Anyway we all know the drill, keep your pricy stuff out of sight and secure your car/truck anyway you can.
