BTW, LoJack is an active transmitter. It is activated from the law enforcement dispatch office. It transmits a unique code. The LEO is essentially engaged in a transmitter hunt with device specific DF gear. It is better than GPS because it does not need a view of the sky. A stolen vehicle from San Diego was located in the living room of a house in Tijuana. Recovering a vehicle from Tijuana is a rare event. It is usually a nice car or SUV that has been stolen for the use of the Federales. If you attempt to retrieve your property from them, you'll spend eternity in a Mexican prison. If the "new" owner is a member of the drug cartel, you'll just end up dead.

Trust me. With children and animals, I will never own a car worth battling a Mexican Cartel over ;)

So then OnStar is different than LoJack? OnStar is GPS and hackable:
