i always figure, if someone is planning to steel it, they'll get it one way or another no matter what you do. really all you are trying to deter is the idiot walking by who wants a joy ride.
on the other hand, Verizon sells an actual GPS/cellular tracking device (VZ Smart Locator) that can be run wired or wireless. $100 with the first year of service free, then $3 a month. that's cheaper than i expected. i'm thinking i'll get one of these and toss it in the jeep or the 55, whatever i'm driving at the time. except they say the battery life is kinda crap, so you can leave it plugged in all the time to use the car battery and only use it's own if someone disconnects it.
