OBD2 + GPS HUD P24 OBD Head Up Display Car Digital Speedometer Fuel Consumption Water Temp Voltage Press Slope Meter With Alarm

Tips:P24 is suitable for 5V-18V.P24 is a dual voltage system, and if the voltage exceeds 18V, the machine will be burned out.We are not responsible for after-sales service if the machine voltage exceeds 18V and burns out.This is a car gauge ,which is connected to the car with a special wire for the gauge.The gauge cannot be directly powered by the mobile phone charging cable.When the screen lights up normally but displays: OBD signal can't be detected!Please start the engine!Your vehicle signal does not match OBD2 or EOBD.Please switch to GPS mode as the product has not malfunctioned.When the following situation occurs with P24, my friend, you can choose GPS mode for use.OBD2 mode function:Vehicle speed, speed, water temperature, voltage, fuel consumption, time average fuel consumption, single driving time, single driving mileage, total mileage, cumulative kilometers per liter, intake pressure, oil temperature, air-fuel ratio column, turbine pressure, intake temperature, oil pressure, throttle valve, engine load, transmission oil temperature, accelerometer G value, up and down slope angle, left and right tilt angleAlarm:Overspeed alarm, speed alarm, water temperature alarm, voltage alarm, turbine pressure alarm, transmission oil temperature alarm, oil temperature alarm, oil pressure alarm, slope alarm, fatigue driving reminder, vehicle fault alarmGPS mode function:Vehicle speed, voltage, time, single driving time, single driving mileage, total mileage, cumulative driving direction, latitude and longitude, number of satellites, altitude, accelerometer G value, up and down slope angle, left and right tilt angle, acceleration test, brake testAlarm:Overspeed alarm, voltage alarm, slope inclination alarm, fatigue driving reminderTip:According to OBD or EUOBD,( the on-board auto-matic diagnosis system) plug and play.If HUD only the car voltage displays and be automatic power off after 30 second(1) This product is only available for OBDII and EOBD cars when it is in OBD2 mode.(2) Year of car production (Suitable for cars produced after 2008).(3)This product OBD2 mode does not support OBD I and JOBD.(4) Switch to the GPS system using the USB cable to display, within 5 seconds of power press right to select the GPS system.(u.s. cars can be used after 2008 and most other cars after 2008.)Package Included:1 x Head Up DisplayPlease read carefully before placing an order:1.If your car is pre-2008, the protocol is not compatible.can not be used.2.After receiving the package, please test it in your car as soon as possible.If you do not want to keep the device after testing, you can also contact us to return it for a full refund.3.
