4' Car I3 HUD Vehicle-mounted Security System with OBD2 Interface

4' Car I3 HUD Vehicle-mounted Security System with OBD2 Interface can project important information onto the front windshield at the eye level of the driver.DESCRIPTION:Features:The head up display (HUD) can project important information (e.g. vehicle speed) onto the front windshield at the eye level of the driver and thus help to make their driving safe and sound when driving at a high speed; especially at night without lowering their heads.1. Automatically adapt to the automobile models with OBD II (Bus Automatic Diagnostic System). 2. Accurate screen digital speed; graphics speed also show. 3. Vehicle speed; engine speed; water temperature; fuel consumption can be read easily. 4. Speed alarm; the remaining oil remind; plus oil remind; voltage; throttle; water temperature; ignition advance angle; one hundred kilometers acceleration; engine fault diagnosis; clear fault codes. 5. Remind driver to shift gear when necessary 6. Compass function.Specification:Material: ABSDisplay Size: 4.0 inchItem size: 105mm*62mm*15mm(host)Item weight: 300gFunction introduction:1.Parameter values: Shows that the value of the unit for km; miles unit; the unit of speed.2.OBDII interface: The data interface to connect to the vehicle.3.Refuel icon: when the volume of oil in the car is not enough to travel 100 km ;the flashing icon will display. 4.Engine failure: When the car computer have broken; the flashing icon will display. 5.Engine speed: Shows the state of the engine speed 6.Speed icon: Shows that the parameter value of the engine is the times of 1000 r;and when the speed alarm at the same time; the icon will flash.7.Speed alarm: When the speed is faster than the its default value; the icon will flash and alarm.8.Rest reminding: When the car run more than 4 hours after launching; the icon will flash and alarm. 9.Voice switch: The icon lights up says that the voice alarm function has been openned.10.Fuel consumption icon: Means that the oil consumption is being calculating. 11.Fuel consumption parameters value: Indicates the consumption of the fuel consumption value in the current driving. 12.Thumbwheel switches: Is a multi-function switch; which can press and move to the left and the right; Long press will enter setup mode; move to the left and the right can quickly fill the car with gas.13.Hour consumption unit: Means the oil consumption of the car per hour 14.Light intensity sensor: Sensing brightness outside and adjust the HUD brightness automatically to adapt to the environment. 15.The fuel consumption of one hundred kilometer: Says the car fuel consumption per hundred kilometer during the process of runing.16.Voltage; throttle; water temperature; the ignition advance Angle; hundreds of kilometers acceleration voltage of bus voltage: Throttle means throttle size; Water temperature means auto cooling fluid temperature; Ignition advance angle indicates the crankshaft of the ignition point of view; is the engine efficiency mark; Hundred kilometers acceleration can test the acceleration performance. 17.The unit S: Means the unit of the acceleration per hundred kilometer.18.The parameter value: Means the parameter value of voltage; throttle; water temperature; the ignition advance Angle; acceleration parameter values per hundred kilometer. 19.Range unit: When fuel only can range 100km; the unit display.20.The rotating speed:The rotating speed of engine; the unit for RPM; numerical x10 display at this time. 21.Km: Means that the current value of the unit for km 22.Miles: Means that the current value of the units for miles. 23.Compass functionINCLUDED:1*Manual1*Reflection Film1*HUD Host1*OBD Cable1*Anti-slip Mat
