Engine Temperature Alarm: Alarm when the water temperature exceeds the set value (the default parameter value is 120℃, and the setting range is 50-200℃)
Engine Speed Alarm: Alarm when the speed exceeds the set value (the default parameter value is 6000R/min, and the setting range is 1000-8000R/min)
Voltage Alarm Setting: Alarm when the voltage is lower than the set value (the default parameter value is 10.5V, and the setting range is 10.0-15.0V)
Speed Error Adjustment: If there is an error in the speed value displayed by the product and the vehicle dashboard, the product parameter value can be adjusted (For example, the vehicle displays 100Km/H, the product displays 105Km/H, the parameter value can be adjusted to 102%)
Speed Reset Setting: The vehicle speed does not return to zero after stalling (For example, if the product displays 5Km/h, the parameter value can be adjusted to 6km/h, and the speed will return to zero)
Voltage Error Adjustment: If there is an error in the voltage displayed by the product and the vehicle dashboard, the product parameter value can be fine-tuned (For example, when the product voltage is 0.2V higher than the vehicle voltage, adjust the parameter value to 98%)
Engine Displacement Setting: If there is an error in the displacement between the product and the vehicle, fine adjustments can be made based on the vehicle displacement (For example, if the vehicle displacement is 3.6L, adjust the parameter value to 3.6L)
Fuel Consumption Data Adjustment: If there is an error in fuel consumption between the product and the vehicle, the product parameter value can be fine-tuned (For example, when the fuel consumption of the product is 0.2L higher than that of the vehicle, adjust the parameter value to 98%)
Brightness Adjustment: “AUTO” refers to automatic light sensitivity, and “1-8” refers to manual adjustment range
Ambient Light Setting: RPM control color changing ambient light / SPEED control color changing ambient light / RED / GREEN / BLUE / YELLOW / BLUE- GREEN / PURPLE / OFF
Temperature Unit Setting: ℃ Celsius ℉ Fahrenheit Speed Unit Setting: km/h MPH
Statistical Mileage Adjustment: The total mileage of both the product and the vehicle is synchronized
Shutdown Delay Setting: The default parameter value is 10 seconds, and the setting range is 5-300 seconds
Shutdown Voltage Setting: When the product cannot be shutdown, the parameter value can be adjusted to 13.2V / 13.6V (Switch to COM mode for automatic start and stop or hybrid vehicles)

right dial to switch to the setting item “System Time Adjustment”. Move the
dial button left and right to adjust, the adjustment range is 30 minutes/time,
and then press and hold the dial button to save and exit
Performance Test
Acceleration test: The acceleration time required for a vehicle speed from 0
to 100 km/h, which is a power test for the vehicle
Braking test: The time and distance used in the braking process after the
vehicle
speed exceeds 100km/h. This function is a performance test for braking
Troubleshooting Setting
Scan fault code: Scan the vehicle for faults and display fault information
Clear fault code: When the vehicle has a fault code displayed, briefly press
the dial button vertically to clear the fault code
FAQ for OBD System:
-
There is no display on the screen and there is no power supply
Please check whether the OBD cable is damaged or replace the vehicle for testing -
The product is powered on, and the screen only displays voltage
Please switch to the GPS system (within 5 seconds of the product being powered on, right dial the dial button to select the GPS system)
[HUD products are only applicable to OBD2 and EOBD (OBD2 and EOBD are only used for vehicles manufactured after 2008)] -
Incorrect vehicle speed
①Please check whether the speed unit is correct km/h or MPH (please refer to the speed unit settings in the setup menu)
②If the speed unit is correct, fine tune the speed (please refer to Speed Error Adjustment in the setting menu) -
Unable to shut down
Enter the system setting, switch to the shutdown voltage setting, and adjust the parameter value to 13.2V / 13.6V (the product will automatically shut down after three minutes of vehicle shutdown) -
Automatic shutdown of the product during driving of the automatic start and stop or hybrid vehicle
①Enter the system settings, switch to the shutdown voltage setting, and then adjust the mode to COM
②Enter the system settings, switch to the shutdown delay setting, and adjust the parameter value to 300 seconds (the product will automatically shut down after five minutes of vehicle shutdown)
③Please switch to the GPS system (within 5 seconds of the product being powered on, right dial the dial button to select the GPS system) -
Operation error leading to product crash
