5. Setup and Installation
- Choose an Optimal Location: For optimal signal reception, install the antenna in an unobstructed location. The roof of the vehicle is generally ideal. Avoid areas that might block GPS signals, such as under metal structures or heavily tinted windows.
- Secure Mounting: The antenna features dual mounting options:
- Magnetic Base: Ensure the magnetic base is firmly attached to a clean, flat metallic surface on your vehicle.
- Screw Mount Option: If a magnetic mount is not suitable, use the screw mounting option for a more permanent installation. (Screws not included, refer to your vehicle's manual for safe drilling locations if applicable).
- Connect to Dash Cam: Plug the 3.5mm male connector of the antenna cable into the corresponding 3.5mm GPS input port on your compatible dash cam. Ensure the connection is secure.
- Cable Management: Route the 3-meter RG174 cable neatly to avoid interference with driving and to prevent damage. If a different cable length is required, please contact the manufacturer for potential customization options.
6. Operation
Once properly installed and connected to a compatible dash cam, the Eightwood Car GPS Antenna operates automatically. It will provide enhanced GPS signal reception to your dash cam for accurate positioning and digital radio reception.
- Voltage Compatibility: Please ensure the dash cam's DC voltage matches the antenna's working voltage (2.7V/3.0V/3.3V/5.0V, etc.) to avoid damaging the product. Refer to your dash cam's specifications for its GPS input voltage requirements.
- Signal Acquisition: Upon powering on the dash cam, the antenna will begin acquiring GPS signals. This may take a few moments, especially during the first use or after a long period of inactivity.
7. Maintenance
- Cleaning: Periodically clean the exterior of the antenna with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Connection Check: Regularly inspect the 3.5mm plug and cable for any signs of wear, damage, or loose connections. Ensure the antenna remains firmly mounted.
- Environmental Exposure: While the antenna is 100% waterproof, extreme conditions can still affect its lifespan. Ensure it is not subjected to unnecessary physical impact.
8. Troubleshooting
