Speed Alarm: the default value is 150 (the default value can be changed, pull down is to decrease, and pull up is to increase, adjust range is 5-200km/h)

Coolant alarm: default value is 120°, it means this device will give alarm when Coolant temperature is over 120° (adjust range is 50-200)

RPM alarm: default value is 6000 r, it means this device will give alarm when RPM over 6000 r (adjust range is 1000-8000)

BAT Alarm: default value is 10.5V, it means this device will give alarm when battery voltage is lower than 10.5V (adjust range is 10.0-15.0V)

Speed Adjust: adjust the speed according to the dashboard, default value is 107% (if the speed is different with the dashboard, then can adjust the value. For example, if the dashboard speed is 100Km/h, and the device speed is 105KM/h, then please adjust the value to 102)

Speed Offset: When the vehicle turns off, but the device speed is not 0, then adjust the device Speed Offset value (if the device speed shows 5KM/H, then change the device Speed Offset default value at 5)

BAT Adjust:  If the battery voltage is different with the vehicle, it can be adjusted.

(if the device voltage is 0.2V higher than the dashboard’s, please change the value to 98%)

Engine Size: if the fuel consumption is much different with the dashboard, please change it as the Displacement size (for example, if the vehicle displacement is 3.6L, please change the default value to 3.6L)

Fuel adjust: default value is 100%, it can be adjusted when the fuel consumption is different with the dashboard. (For example, if the device fuel consumption is 0.2L higher than the dashboard, please adjust it to 98%)

Error code set

Scan DTCs: scan the ECU to check if there is the error code and show the error details

Clean DTCs: switch to clean the DTCs, short press in the button to finish the cleaning


Data Stream

Show the entire vehicle data stream



It is recommended to unplug the device if your car doesnt been used for more than one week.



  1. The screen without any display and no power

Start the car engine; check if the OBD cable line is tight; please pull down the OBD cables more times to ensure; check if product power switch turns on. If still no display, please change another car to test, analyze whether the car OBD diagnostic interface is good, if it is not good, please repair it and try again.


  1. Only shows the car voltage and be automatic power off after 30 second when the device is with power

This product just available for cars with OBD2 agreement and EU-OBD agreement (European region: after 03 years, other region: after 07 years)

This Product do not support JOBD and OBDI and recommended test for another car.


  1. Inaccurate Speed
  2. First check the speed unit is correct or not, the speed unit including KM/H and MPH, please refer to the setting to switch the unit.
  3. When the product is power on, long press in the button to enter into the menu option, pull right the button to choose the speed adjust, short press in the button to set the value, pull left or right to change the value. (If the dashboard shows 100 and the device show the 105, change the default value at 102)


  1. Inaccurate Fuel consumption

Check your car displacement and set the device same as your car (if your car is 2.0L, then change the device value at 2.0L). The fuel consumption can be adjusted, but we don’t suggest changing it, because all the data’s are read from the car ECU directly.


  1. The device cannot auto power off

Adjust the sleep voltage to 13.2V or 13.6V, then HUD will power off in 3 minutes.



  1. Auto start- stop cars

Change the Power off time to 180s or 300s


  1. HUD crashes in driving, or Hybrid car

Change the power off time to 180 or 300. If still can’t solve, please switch to GPS system.


  1. Wrong operation lead to crashes
  • Please check the OBD interface if connected with other device
  • Modified and retrofitted cars will cause a crash

Please remove other OBD devices and do the factory reset.


  1. Inaccurate Time

Long press in the button to enter into the menu setting, pull right to find the time adjust, short press in to choose the option, pull left to set the hour, pull right to set the minutes.
