OBD FAQ：

1.The screen without any display, and no power

Check whether the OBD cable is tight connection, pull down repeatedly to confirm,

please try it on another car if still not workable, analysis if it is a cause from OBD

diagnostic interface, if yes, please repair it and connect the device again.

2.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.

3.There is an error between the vehicle speed and the dashboard display

Please check whether the unit is correct. Kilometer KM/mile MPH (reference setting

item for speed unit switching)

The speed unit is correct when the power is turned on: long press in to enter the

setting, press right to select the speed error adjustment for fine-tuning (e.g.

instrument display 100 Km/h HUD shows 105Km/h, use default value 107-5=102)

4. There is an error in fuel consumption

(1) 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)

(2) 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

5.This HUD cannot auto shut down

After the car engine stops,the RPM on the HUD can not be turned off,please set

voltage to 13.2V or 13.6V,so that the car can be turn off after 3 minutes.

6. Step on the brakes and wait for the traffic light to turn off the machine and

automatically start and stop the car.

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

7. Automatic start-up will auto off when step the brake and same situation on

Hybrid car in the traffic.

(1) Setting to COM mode(in the menu of shutdown voltage)

(2) Setting shutdown delay to 300 seconds,so that it can turn off after 5 minutes

(3) Please switch to the GPS system(right press within 5s)

8. Wrong operation leads to crash.

(1) Whether the OBD2 interface uses other OBD devices (locator, tire pressure

monitoring, drop lock lift window folding ELM27).

(2) Modified and installed (central control navigation, electronic throttle controller,

cruise control, brushed computer system ，One-key startup，keyless entry, remote

startup) will cause crashes, unplug other OBD devices and use this product directly to

restore factory settings (see the setting table for details).

(3) Long press in to enter the setting, press right to select restore factory settings,

short press in to confirm.

If it is not resolved, please switch to the GPS system for display, and press right for 5

seconds to select the GPS system.

GPS Display FAQ：

1.Nothing on the screen,no power

Check whether the OBD cable is tightly connected, pull it out and plug it in several

times, or plug USB cable into cigarette smoker.

2.No speed

The GPS is flashing to search for stars. Please move the car to an open road. GPS

display above 5 means it can be used normally only after searching 5 satellites.

3. Can not automatically turn on or turn off repeatedly during driving

If you use OBD cable, enter the setting menu to select the “Sleep Voltage” and adjust

the parameter value voltage to 13.0V or 12.8V.

4.Inaccurate satellite time

Enter the setting item: Time Adjust, press right to adjust the time zone time, after

adjustment, long press in to save and exit.

5.Inaccurate vehicle speed

(1) Check whether the unit is correct, kilometers KM/mile MPH (speed unit switch

please refer to the settings mode “speed unit”).

(2) When the car leaves the factory, the manufacturer increases the speed displayed

on the dashboard by 5-7%. International standards are based on satellite data.

(3)Fine-tune the vehicle speed, such as the instrument display 100 Km/h HUD display

105Km/h dial on the dial to adjust the parameter value to 102.

6.Wrong driving direction

Satellites can not read your driving direction when there is no speed. It will be

normal until >5KM/H.

7.Speed is still on after the car stops

Underground parking lots, tunnels, and overpasses, when there are obstructions, the

signal will be unstable. Satellites will drift. Please drive to an open road. If the

number of satellites found is more than 5, it will be normal.

8. After the car is turned off, it will not automatically shut down

When the OBD cable is connected, the machine will automatically shut down after 3

minutes

If the machine has not shut down after 5 minutes after stopping the flame, adjust the

parameter value of the shutdown voltage setting to 13.5V.
