Certification:NONE Origin:Mainland China OBD2+GPS+Slope Meter HUD Smart Gauge Speed RPM BAT alarm Acceleration&Brake test Scan fault code OBD2+GPS+Slope Meter HUD Smart Gauge Speed RPM BAT alarm Acceleration&Brake test Scan fault code This product reads the driving data of the car through the OBD2 interface of the car ECU, such as vehicle speed, rotation speed, fuel consumption, water temperature and voltage, etc., Instantly read driving information under the condition that drivers view does not shift during the driving of the car.To keep the drivers eyes on road always to avoid the dangerous of lowering down head. This product does not rewrite any data in the ECU. Speed Alarm: Alarm when the vehicle speed >150km/h, the setting range is 5-200 km/h Coolant Alarm: Alarm when the water temperature >120C, the setting range is 50-200 RPM Alarm: Alarm when the engine speed >6000r/min, the setting range is 1000-8000 BAT alarm: Alarm when the voltage Speed Adjust: Adjust the parameter value when there is an error between the speed and the instrument panel (for example, the instrument displays 100 Km/h and the device displays 105Km/h, and the parameter value is adjusted to 102 on the dial) Speed Offset: When the vehicle speed does not return to 0 after the car is turned off (If the vehicle speed shows 5Km/h, the equipment is adjusted to 6Km/h) BAT Adjust: When there is an error between the voltage and the instrument panel voltage, fine adjustment can be made (If the device displays 0.2V higher than the instrument voltage, the device is adjusted to 98%) Engine Size: When the fuel consumption error is large, adjust according to the displacement (If the car displacement is 3.6L, adjust the parameter value to 3.6L) Fuel Adjust:Fine-tuning when there is an error in fuel consumption (If the device displays 0.2L higher than the instrument voltage, the device is adjusted to 98%) Brightness Auto= Automatic light sensitivity, 1= The darkest, 8 =The brightest Atmosphere: RPM = Speed control color-changing atmosphere light SPEED= Car speed control color-changing atmosphere light OFF= Turn off the atmosphere light BLUE= Blue atmosphere light RED= Red atmosphere light PURPLE=Purple atmosphere light CWT UnitC =Celsius F =Fahrenheit Speed Unit : Km/h= Kilometers MPH= Miles Sum Distance: Synchronization of total mileage (For example, the total odometer on the dashboard shows that you have driven 30010km, adjust the parameter value to 30010km) Power Off Time:The default is 10 seconds to shut down, the adjustment range is 5-300 seconds Sleep VoltageAdjust to 13.2V or 13.6 when unable to shut down, adjust to COM mode for cars that start and stop automatically Time Adjust: It can be adjusted to local time, the default time is China time (GMT+8) Factory Set: The system restores to the factory preset values. After selecting this operation, short pressMButton to confirm Note: Some cars cannot be used in OBD2 mode,that are recommended to be used in GPS mode. GPS mode is suitable for all cars Applicable models in OBD2 mode: The scope of application of OBD2 models: most of the OBD2 agreement gasoline vehicles produced in the United States after 2004, and most of the OBD2 agreement gasoline vehicles produced in other regions after 2008 OBD2 mode is not applicable to the following common models: OBD 2 models that cannot be used in the U.S. series: Dodge, JEEP, Sail, Chrysler, and models produced before 2004 and 2004 All French and Italian models of OBD2 cannot be used: such as: Fiat, Maserati, DS, logo, Citroen, Renault, Simca, Amirka, etc. OBD 2 Japanese models that cannot be used: Suzuki, Mazda 3/6, Infiniti (QX50 q50 q501), 2013 Toyota avanza, Lexus (is250, ex250, ES300H) Honda (jazz, CRV) and cars produced before 2008. Some Korean Kia and Hyundai models cannot use OBD models (2013 Hyundai Sonata, 2017 Kia Soul PS, etc.) It is recommended to use the GPS mode for hybrid gasoline-electric vehicles, diesel vehicles, pickup trucks, RVs, and modified car computers.
