OBD2 System Troubleshooting

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.

2. Only the car voltage displays and be automatic power off after 30 second

3. This product is only available for OBDII and EOBD cars when it is in OBD2 mode

4. This product OBD2 mode does not support OBD I and JOBD

5. OBD2 is a car protocol(U.S.A Cars:2003 Other regions:2007)

6. Switch to the GPS system , within 5 seconds of power Pull right the button to select the GPS system.

7. Inaccurate Speed

8. 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.

9. 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 shows the 105,change the default value at 102)

10. There is an error on fuel consumption

11. Checking your car displacement and make sure that the engine displacement of the device is as same as your car’s(e.g. car is 2.0L, please set parameter value to 2.0L)

12. if the displacement is the same, you can also do a fine-tuning settings(e.g. equipment fuel is higher than 0.2L, please set the parameter to 98%) Recommended: fine-tuning is optional since it is a real data from car computer

13. The device can not auto power off
    Adjust the sleep voltage to 13.2V or 13.6V, then HUD will power off in 3 minutes.

14. Auto start- stop cars
    Adjust the shutdown voltage setting in the system settings to the COM mode

15. HUD crashes in driving,or Hybrid car

16. Adjust the shutdown voltage setting in the system settings to COM mode

17. If it is not resolved, adjust the shutdown delay setting in the system settings to 300 seconds, and shut down after 5 minutes after the car goes out.

18. If it is not resolved, please switch to the GPS system for display. Within 5 seconds after the power is turned on, select the GPS system.

19. Wrong operation lead to crashes

20. Does the OBD2 interface use other OBD equipment (positioner, tire pressure monitoring, drop lock, lift window folding, ELM27)

21. Modified and retrofitted (central control navigation electronic throttle accelerator fixed speed cruise brushed computer system

22. One-key start, keyless entry, remote start) will cause crashes, unplug other OBD devices and use the product directly, to restore factory settings (see the setting table for details)

23. Press and hold the scroll wheel to enter the setup menu, right-click the scroll wheel to switch to system settings, press the scroll wheel vertically to enter the system settings, right-click the scroll wheel to switch to factory settings, and press the scroll wheel vertically to confirm.

24. If you haven’t solved it, please switch to GPS system . Turn on the power and turn the dial for 5 seconds to select the GPS system.

GPS System Troubleshooting:

1. The screen without any display, and no power
   Start the car engine; check if the cable line is tight;

2. Without car Speed
   After HUD power-on, the GPS will start to find the satellite. Please drive the car to the road. It will work once gets more than 5 satellite signals.

3. Cannot be turned on automatically or repeatedly extinguished during driving
   Change the sleep voltage to 13.0V or 12.8V

4. Inaccurate time
   Enter the setting items: system time adjustment, turn the dial to the right to adjust the time zone
   time, after adjusting, press the dial vertically shortly for 2 seconds to save and exit

5. Inaccurate Speed

6. 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.

7. The car manufacturers usually make the dashboard speed 5-7% higher than the ECU. The international standard is based on satellite data.
   (if the dashboard shows 100,and the device shows the 105,change the default value at 102)

8. Driving direction display error
   After the vehicle speed exceeds 5KM / H, the direction can be displayed normally.

9. Speed is still displayed after the car stops
   Under the underground parking lot, tunnel, under the overpass, there will be unstable satellite drift when there is obstruction. Please drive the vehicle to the empty road. The number of satellites found is more than 5 and it shows normal.

10. The device cannot auto power off when the car is turned off

11. If connects by OBD cable, it will auto power off in 3 minutes.

12. If it still not powers off in 5 minutes, please change the sleep voltage to 13.5V
