4. Setup and Installation
This adapter is designed for easy installation. Follow these steps to connect the aux input adapter to your car radio:
- Prepare Your Vehicle: Ensure your car's ignition is off. If necessary, disconnect the car battery's negative terminal to prevent electrical shorts during installation.
- Access the Car Radio: Carefully remove your car radio from its dashboard slot to access the rear connections. This usually involves removing trim panels and screws. Refer to your car's specific service manual for detailed instructions on radio removal.
- Locate the IP BUS Port: On the back of your Pioneer car radio (models AVIC Z1, Z2, Z3, N4), locate the IP BUS port. This is typically a multi-pin connector designed for CD changers or other external accessories.
- Connect the Auxiliary Adapter: Plug the black IP BUS connector of the auxiliary adapter cable firmly into the IP BUS port on your car radio. Ensure it clicks securely into place.
- Route the 3.5mm Jack: Route the 3.5mm female end of the auxiliary adapter cable to a convenient location in your dashboard or center console where you intend to connect your audio device. Ensure the cable is not pinched or exposed to excessive heat.
- Reconnect and Test: Reconnect your car battery (if disconnected) and reinsert the car radio into its slot. Turn on your car and the radio.
- Connect Audio Device: Use the provided red 3.5mm auxiliary cable to connect your audio device (e.g., smartphone, MP3 player) to the 3.5mm female jack of the installed adapter.

5. Operating Instructions
Once the adapter is installed and your audio device is connected:
- Select AUX Input: On your Pioneer car radio, navigate through the source options (e.g., FM, AM, CD, USB) until you find and select the "AUX" or "CD Changer" input. The exact label may vary depending on your specific Pioneer model. This input is typically enabled when the IP BUS adapter is detected.
- Play Audio: Start playing music or audio from your connected device (smartphone, MP3 player).
- Adjust Volume: Control the volume primarily through your car radio's volume knob. You may also need to adjust the volume on your connected audio device for optimal sound quality.
Note: This adapter provides audio input only. Control of music playback (e.g., track skipping, play/pause) must be done directly on your connected audio device.
6. Maintenance
The EVTSCAN Aux Input Adapter requires minimal maintenance to ensure long-lasting performance:
- Keep the cables and connectors clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid sharp bends or kinks in the cables, as this can damage the internal wiring.
