I thought it would be some pathetic excuse like that.

thats why i will stick with having my 2 trackers. covered for every eventuality then. Tracker can refuse to tell me anything if they want and i will just live track my other tracking unit.

Might get a third externally hidden unit. Wont be able to jam that as its outside the farraday cage that is the shell.

those GSM/GPS trackers are not very good, they only kill the signals inside the shell and from when i played around with one, if the aerial is close enough to a window it still wont stop the car getting a gps fix on the later gen 2 and gen 3 satellites that have slowly replaced the old GPS satellites; the jammers are targetted on the frequencys used on the early gen 1 GPS systems. the battery powered ones are expensive and the cigarette lighter ones rely on you having a cigarette lighter in the car......
