This unit costs hundreds of dollars less than others that we've seen, and it's received lots of positive feedback! Your new covert GPS vehicle tracking device may be used for monitoring the travel activities of company, fleet, and private vehicles. It doesn't require complicated wiring or GPS antenna mounting. Included are 4 "AA" batteries that will power the unit for about 3 months. To track the vehicle, all you need to do is access the Trim Track website from any computer with Internet access. The information about the vehicle is updated every five minutes (default, may be modified according to your needs) and includes the time, vehicle speed, street address of vehicle and last stop. There is also a toll-free customer support number where you can call and ask questions!
