4. Setup and Installation
The SinoTrack HUD offers non-destructive, plug-and-play installation.
- Placement: Choose a suitable flat surface on your dashboard where the HUD will not obstruct your view or interfere with airbags. The non-slip mat can be used to secure the device.
- Power Connection: Plug the Micro USB cable into the Micro USB port on the back of the HUD unit.
- Vehicle Power: Connect the other end of the USB cable to a USB power source in your vehicle, such as a cigarette lighter adapter with a USB port or a built-in USB port.
- Cable Management: Route the USB cable neatly to avoid entanglement and ensure it does not interfere with driving. You can insert the wire into the A-pillar seal for a cleaner look.
- Power On: The device will automatically power on when it receives power from the vehicle and power off when the vehicle is turned off (if the USB port is ignition-switched).
- GPS Signal Acquisition: Upon first use, the device may take a few minutes to acquire GPS satellite signals. Ensure the device has a clear view of the sky for optimal signal reception.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power from USB port; faulty cable; incorrect voltage. | Check USB connection and power source. Ensure 5V power supply. Try a different USB port or cable. |
| No GPS signal / Speed not displayed. | Obstructed view of sky; initial signal acquisition; driving in tunnels/garages. | Move to an open area with clear sky view. Allow a few minutes for signal acquisition. GPS signal may be temporarily lost in certain environments. |
| Speed reading is inaccurate. | Calibration needed. | Refer to the detailed settings in the user manual (not covered in this summary) for speed calibration. Some minor discrepancies with vehicle's odometer are normal. |
| Display is too dim or too bright. | Automatic brightness sensor blocked; manual setting needed. | Ensure the photosensitive element (small hole on the back) is not blocked. Adjust brightness manually as described in section 5.3. |
| Trip distance resets after power off. | Normal operation. | This is an intended feature. The device relies on continuous power to track trip distance and does not accumulate total distance when powered off. |
