This is the worst company for GPS out there. Steer clear of their smooth talking sales people who promises the world but deliver dog *** You will get a better ROI if you throw it in the trash because the units do not work properly and you will have to pull your trucks back off the road. I can not wait to change. I called to talk to Customer service and they transferred me to sales. Talked with Omar who gave me a bunch of smoke and told me he would call me back. Never heard from him again. its the same story here everytime. No one takes accountability for anything. i would rather drive my car off a cliff than do business with Teletrac again!
