Introduction
This manual provides instructions for the installation and operation of your IMC Audio Ai-net to 3.5mm Aux Input Cable. This cable allows you to connect external audio devices, such as smartphones or MP3 players, to compatible Alpine head units equipped with an Ai-net port, enabling audio playback through your car's sound system.
Setup and Installation
Before beginning installation, ensure your vehicle's ignition is off and the car battery is disconnected to prevent electrical damage.
- Locate the Ai-net Port: Identify the Ai-net port on the rear of your Alpine head unit. This port is typically a multi-pin connector. You may need to remove the head unit from its mounting to access the rear panel.
- Connect the Ai-net Cable: Carefully plug the Ai-net connector of the IMC Audio cable into the corresponding Ai-net port on your Alpine head unit. Ensure a secure and firm connection.
- Route the 3.5mm Cable: Route the 3.5mm auxiliary end of the cable to a convenient location within your vehicle, such as the glove compartment, center console, or dashboard, where your audio device will be placed. Ensure the cable is routed safely and does not interfere with vehicle operation.
- Reconnect Power: Once the cable is securely connected and routed, reconnect your car battery and turn on the vehicle's ignition.
