Product Overview
The KAOLALI G13 GPS Head-Up Display (HUD) is designed to enhance driving safety by projecting essential vehicle information directly into the driver's line of sight. This allows drivers to monitor key data such as speed, time, and driving direction without diverting their attention from the road.
Equipped with a 2.2-inch full HD LCD screen, the G13 offers clear, large-font displays with multiple color options for personalization. Its built-in light sensor automatically adjusts screen brightness for optimal visibility day or night. The device is universally compatible with all car models, featuring a simple plug-and-play USB power supply and flexible installation options including a 360-degree rotating suction cup mount and an anti-slip mat.

Operating Instructions
The G13 HUD features a multi-function display and intuitive controls for easy operation.
Display Functions:
The G13 can display various information, including:
- Speed: Current driving speed (KM/H or MPH).
- Clock: Current time.
- Speed + Clock: Displays both speed and time simultaneously.
- Satellites Number: Indicates the number of GPS satellites connected for accurate positioning.
- Driving Distance: Total distance traveled during the current trip.
- Driving Time: Total time spent driving during the current trip.
- Driving Direction: Compass display (N, S, E, W).

Switching Display Interfaces:
The G13 offers 7 different display interfaces. To switch between them, press the dial button located on the top of the unit vertically. Each press will cycle through the available display modes.
Automatic Brightness Adjustment:
The built-in photosensitive element automatically detects ambient light and adjusts the display brightness accordingly. This ensures the display is visible during the day and soft/non-glaring at night.

Alarm Functions:
The G13 includes two important alarm functions for enhanced safety:
- Overspeed Alarm: Alerts you when your vehicle exceeds a preset speed limit. This limit can be adjusted in the settings.
- Fatigue Driving Reminder: Provides a reminder after 8 hours of continuous driving to encourage breaks.

Color Customization:
The display offers 6 different color themes that can be switched to your preference. Use the dial button to navigate through color options in the settings menu.

Troubleshooting
If you encounter issues with your KAOLALI G13 HUD, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device not powering on | No power supply or faulty USB cable/port. | Ensure the USB cable is securely connected to both the HUD and a working USB power source in your vehicle. Try a different USB port or cable. |
| Inaccurate speed reading | GPS signal interference or initial calibration. Note: The HUD's displayed speed may be slightly higher than actual speed for safety. | Ensure the device has a clear view of the sky for optimal GPS signal reception. Drive for a few minutes to allow the GPS to stabilize. If the discrepancy is significant, you may be able to adjust the speed calibration in the device settings (refer to the detailed manual for specific steps). |
| Display too dim or too bright | Automatic brightness sensor obstructed or malfunctioning. | Ensure the photosensitive element (located on the top of the unit, as shown in the diagram) is not covered. Clean the sensor if necessary. |
| No GPS signal/Satellites not found | Device is indoors, in a tunnel, or obstructed view of the sky. | Move the vehicle to an open area with a clear view of the sky. Wait a few minutes for the device to acquire GPS satellites. |
Maintenance
To ensure the longevity and optimal performance of your KAOLALI G13 HUD, follow these maintenance guidelines:
