Thats the big problem I have with it.Unless the tech didnt know he was being followed he is going to skirt the system.Case in point a new tech van shows to be in a county he is in a diffrent county at customer suposedly.He had a part I needed on his van if he was where he was supposed to be it would have been 25 miles.Trick found pull fuse it kills gps and you show to be at place fuse is pulled.How do I know that?His van swaped locations 30 min after I called and started heading for me.Tech there 1 month.You know he didnt drive 125 miles to get his unit then get to where he said he was in 30 min.When asked about it he didnt know what was going on.Serval ufo movings have been reported. Beam me up Scotty.
