I have the LoJack in the UK car for the last 13 years. Still works. and there is nationwide coverage.
The LoJack web site displays the counties in each state where there is coverage. In Arizona, only the high density areas are covered which makes it useless in the rest of the state. The border areas are not covered from what I read, which is where most stolen vehicles are headed.
