Well I say don't waste your money why you ask? Well the tundra isn't a big theft target and here is my personal reason I will never buy another LoJack unit ... I always find the units in easy to find locations when I am working on customers cars and the biggest reason is that 2 1/2 weeks ago my civic si was stolen and they still haven't found it ... LoJack was notified right away and still no recovery .... I wasted 700 bucks buy it if you want to but I won't make this mistake again
