4. Setup and Installation
This section outlines the general steps for installing the digital TV film antennas and GPS metal sheet. Refer to your car navigation system's specific installation manual for detailed wiring diagrams and panel removal instructions.
4.1. Preparation
- Clean the inner surface of the windshield where the film antennas will be applied using the provided cleaner. Ensure the surface is dry and free of dust, grease, and moisture.
- Identify the correct placement for each film antenna (A, B, C, D) as indicated on the antenna sheets and in your navigation system's manual. Typically, these are placed on the upper corners of the windshield.
4.2. Film Antenna Installation
- Carefully peel off the backing from one film antenna, avoiding touching the adhesive surface.
- Align the antenna precisely on the designated area of the windshield. Press firmly from the center outwards to remove any air bubbles.
- Repeat for all four film antennas.
- Connect the corresponding antenna cords to the film antennas. Ensure a secure connection.
4.3. GPS Metal Sheet Installation
The GPS metal sheet is designed to enhance the reception and accuracy of your existing GPS antenna. It should be placed directly underneath your GPS antenna, typically on a flat, non-metallic surface within the dashboard or under the windshield.
- Identify a suitable, flat location for your GPS antenna.
- Clean the surface where the GPS metal sheet will be placed.
- Peel off the backing from the GPS metal sheet and adhere it to the cleaned surface.
- Place your existing GPS antenna directly on top of the installed GPS metal sheet.
4.4. Cable Routing and Connection
- Route the antenna cords from the film antennas along the vehicle's pillars and dashboard, ensuring they are hidden and secured with the provided clips.
- Connect the antenna cords to the corresponding input ports on your Panasonic Strada car navigation system. Refer to your navigation system's manual for port identification.
- Ensure all connections are firm and properly seated.

5. Operating Instructions
Once properly installed, the digital TV film antennas and GPS metal sheet operate passively to enhance your car navigation system's performance. There are no specific user operations required for these components themselves.
- Digital TV Reception: Turn on your car navigation system and select the digital TV function. The installed film antennas will provide improved signal reception.
- GPS Positioning: The GPS metal sheet works in conjunction with your existing GPS antenna to provide more stable and accurate location data to your navigation system.
For detailed instructions on operating your car navigation system's digital TV and GPS functions, please refer to the navigation system's user manual.
6. Maintenance
These components require minimal maintenance to ensure long-term performance.
- Cleaning: Periodically inspect the film antennas on the windshield for dirt or smudges. Clean gently with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the film.
- Inspection: Regularly check the antenna cords and connections for any signs of wear, damage, or looseness. Ensure they remain securely fastened.
- Environmental Factors: Extreme temperatures or prolonged exposure to direct sunlight can affect adhesive longevity. While designed for automotive use, avoid unnecessary exposure to harsh conditions.
7. Troubleshooting
If you experience issues after installation, consider the following troubleshooting steps:
- Poor Digital TV Reception:
- Check all antenna cord connections to the film antennas and the navigation system. Ensure they are secure.
- Verify that the film antennas are correctly applied to the windshield without air bubbles or damage.
- Ensure there are no metallic objects or window tinting interfering with the antenna's signal path.
- Test reception in different locations, as signal strength can vary geographically.
- Inaccurate or Unstable GPS Positioning:
- Confirm that the GPS metal sheet is placed directly under your GPS antenna.
- Ensure the GPS antenna itself is positioned in a location with a clear view of the sky (e.g., dashboard, not under metallic objects).
- Check the connection of your GPS antenna to the navigation system.
- No Power to Navigation System: This kit does not provide power. If your navigation system has no power, check its main power connections and fuses, referring to its specific manual.
If problems persist after attempting these steps, consult a professional installer or contact Panasonic customer support.
