- Route the Cable: Carefully route the OBD2 cable from the interface to the desired mounting position for the HUD unit, ensuring it does not interfere with driving controls.
- Connect HUD: Plug the OBD2 cable into the HUD host.
- Secure HUD: Place the HUD host on the dashboard using the provided non-slip pad to ensure it is stable and does not move during driving.

Operating Instructions
The Vjoycar HUD features a user-friendly interface with a main button for navigation and adjustments. The device will automatically power on and display information after starting the car.
Menu Navigation and Value Adjustment:
The HUD has a main button (often referred to as a scroll wheel or push button) that allows you to navigate through settings and adjust values. The user manual (included in the package) provides a detailed comparison table for menu items and their corresponding values.
- Entering Settings Mode: Long push the main button inward to enter the settings mode.
- Changing Menu Items: While in settings mode, push the button inward to cycle through menu options.
- Adjusting Values: For a selected menu item, push the button left or right to change its value.
- Exiting Settings: Long push the button inward again to save changes and exit the settings mode.
Example Adjustments:
Changing Speed Unit (KM/H to MPH):
- Long push the main button inward to enter settings mode.
- Push the button inward repeatedly until you reach the "Speed Unit" setting (Menu item 22).
- Push the button left or right to change the value from '0' (KM/H) to '1' (MPH).
- Long push the button inward to save and exit.
Calibrating Speed:
If the HUD speed display differs from your car's actual speed (e.g., car speed 80km/h, HUD 75km/h), you can adjust the speed value:
- Long push the main button inward to enter settings mode.
- Push the button inward repeatedly until you reach the "Speed" setting (Menu item 0).
- Push the button left or right to adjust the value (e.g., from 105 to 100 to match the car's speed).
- Long push the button inward to save and exit.

Troubleshooting
Common Issues and Solutions:
- HUD does not power on: Ensure the OBD2 cable is securely connected to both the HUD unit and the vehicle's OBDII port. Check vehicle ignition status.
- Inaccurate Speed Display: Refer to the "Calibrating Speed" section under Operating Instructions to adjust the speed value.
- Display is too dim/bright: The HUD features automatic brightness adjustment. If manual adjustment is preferred, enter settings mode and navigate to the "Brightness" setting (Menu item 8) to adjust the level (1-11).
- No Display or Partial Display: Check the reflective film placement. Ensure the HUD unit is positioned correctly.
- Incompatibility with Vehicle: The OBD2 working mode may not be compatible with certain vehicles. This includes almost 98% of cars manufactured before 2004, some old oil/electric hybrid cars, diesel-powered cars, pickup trucks, SUVs, ORVs, mini buses, and a few other special car models.
- RPM Alarm Flashing: This indicates the engine RPM has exceeded the set alarm value.
- Coolant Alarm Flashing: This indicates the engine coolant temperature has exceeded the set alarm value.
