1.the chip is ARM chip which speed is more faster and the communication speed is doubled than before one（CLK DEVICE）
2.the shape looks elegant and refined, the design is near the Apple style,compared the （CLK DEVICE）,this new device is more exquisite,it doesn’t using the cable but （CLK DEVICE）having.
3.It has the function of power be off and energy keeps saving automaticly.When the main chip were detected not in communication for an hour then the device  will be off automaticly and get into energy saving state,it only comsumes 3 microamp electric current which saved much for the cars power supply system.
4.the real J1939 and the stable J1979 protocol can make customers  do efficiently redeveloped
5.it supports all WIFI System (ANDROID, PC，WINCE，IPHONE，IPAD)
6.it distributes address freely not same as the traditional ADHOC do,so customer can make a clear and simple connecting.
