3. Setup and Installation
Follow these steps carefully for proper installation of your GPS speedometer.
3.1 Panel Mounting
- Cut a 52mm (2 1/16") diameter hole in the desired panel location. Ensure a clearance of at least 70mm (2 3/4") behind the panel for the gauge to fit.
- Insert the gauge into the prepared hole.
- Secure the gauge using the provided M4 nut and C-type bracket to seal it firmly in place.

3.2 GPS Antenna Connection
- Securely fasten the GPS antenna in a flat position with the black side facing upwards. For optimal signal reception, place it outside or inside the front windscreen, ensuring a clear view of the sky.
- Connect the antenna cable to the designated socket at the back of the gauge. Do not cut the antenna cable.
- Upon initial power-on, the GPS speedometer may take approximately 30 seconds to acquire a signal. Subsequent signal acquisition will typically take less than 3 seconds, especially under clear skies.

4. Operating Instructions
4.1 Display Information
The speedometer displays the current speed and the accumulated odometer (ODO) reading. The ODO value is accumulated and does not reset when power is turned off.
4.2 Adjusting Units
To switch between speed units (KM/H, MPH, KNOTS), press the black button located on the back of the gauge. Each press will cycle through the available units. The selected unit will be saved automatically.

5. Maintenance
The ELING GPS Speedometer Odometer is designed for durability and requires minimal maintenance. To ensure longevity and clear readings:
- Regularly clean the display with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Ensure all electrical connections remain secure and free from corrosion.
- Periodically check the GPS antenna placement to ensure it maintains a clear view of the sky for optimal signal reception.
6. Troubleshooting
If you encounter issues with your GPS speedometer, refer to the following common problems and solutions:
Error Codes:
- E01: GPS cannot search for a GPS signal when powered on.
- E02: GPS signal lost during operation.
- E03: The internal circuit of the instrument is faulty.
General Troubleshooting Tips:
- No Display/Power: Check all wiring connections, especially the power (red) and ground (blue) wires, to ensure they are secure and receiving the correct voltage (9-32VDC).
- No GPS Signal (E01/E02): Verify that the GPS antenna has a clear, unobstructed view of the sky. Ensure the antenna cable is securely connected to the gauge and is not damaged. Move the vehicle to an open area if indoors or under heavy cover.
- Incorrect Readings: Ensure the correct unit (KM/H, MPH, KNOTS) is selected. If readings are consistently inaccurate, recheck the GPS antenna placement.
- Display Issues: If the display is dim or flickering, check the power supply. If an E03 error occurs, the internal circuit may be faulty, and professional assistance or replacement may be required.
