GT3600 is designed for taxi and logistics management purposes. The new SiRF Star III Global Positioning System receiving module is employed in the unit to provide fast and accurate positioning functionality. Moreover the newest quad-band GSM module is built in the unit for sending vehicle's location information to server, and receiving commands or parameters from server. GT3600 is therefore suitable to be used almost around the world. Besides, GT3600 can be connected to panic button, car alarm system, or some kind of switches and sensors. GT3600 is able to break the ignition circuit and electricity of fuel pump. The best quality and powerful functions are the goals that we pursue, so that all components in the GT3600 are industrial standard compliant, and some advanced AVL functions have been built in the GT3600, such as Towing alert, Geo-Fencing, and also navigation function (with this the driver doesn't know how many vehicles at the same area, but also know its job status^) Hope you will like it.
