Setup and Installation

Follow these steps to properly install your Bluetooth adapter:

Disconnect Vehicle Power: Before beginning, ensure the vehicle's ignition is off and the negative terminal of the car battery is disconnected to prevent any electrical issues.
Access Head Unit: Carefully remove your Alpine head unit from the dashboard to access the rear connections. Refer to your vehicle's service manual or an online guide for specific instructions on how to remove your particular head unit model.
Locate Auxiliary Input: Identify the auxiliary input port on the back of your Alpine head unit. This is typically a multi-pin connector. The EASWEL adapter is designed to connect directly to this port.
Connect Adapter: Plug the blue multi-pin connector of the EASWEL Bluetooth adapter into the corresponding auxiliary input port on the Alpine head unit. Ensure it is securely seated.
Connect Power:
- Connect the red wire of the adapter to a 12V accessory power source (ACC) in your vehicle. This source should only be active when the ignition is on.
- Connect the black wire of the adapter to a reliable ground point in your vehicle chassis.
Note: Proper power connection is crucial for the adapter's functionality. Incorrect wiring can damage the adapter or your vehicle's electrical system. If unsure, consult a professional installer.
Secure Wiring and Reinstall Head Unit: Once all connections are made, carefully route the adapter and its wires to avoid pinching or interference. Reinstall your Alpine head unit back into the dashboard.
Reconnect Vehicle Power: Reconnect the negative terminal of your car battery.

Operating Instructions

Once the adapter is installed and powered, follow these steps to use it:

Turn on Head Unit: Power on your Alpine head unit.
Select AUX Source: On your Alpine head unit, select the auxiliary input source. This may be labeled "AUX", "AI-NET", "CD Changer", or similar, depending on your specific Alpine model. Refer to your Alpine head unit's manual for exact instructions on selecting the auxiliary input.
Pair Bluetooth Device:
- On your smartphone or other Bluetooth-enabled audio device, go to the Bluetooth settings.
- Enable Bluetooth and scan for available devices.
- Look for a device named "EASWEL" or similar (the exact name may vary). Select it to pair.
- Once paired, your device should indicate a successful connection.
Play Audio: Start playing audio from your paired device. The sound should now be transmitted wirelessly to your Alpine head unit and play through your car's speakers.
Control Playback: Use your paired device to control music playback (play/pause, skip tracks, volume). The volume can also be adjusted via your Alpine head unit.

Maintenance

Cleaning: Use a soft, dry cloth to clean the adapter if necessary. Do not use liquid cleaners or solvents.
Storage: If the adapter is removed from the vehicle for an extended period, store it in a cool, dry place away from direct sunlight.
Cable Integrity: Periodically check the wiring for any signs of wear, fraying, or damage. Ensure connections remain secure.

Troubleshooting

Problem	Possible Cause	Solution
No power to the adapter.	Incorrect power wiring (red/black wires). Blown fuse in vehicle's accessory circuit.	Verify the red wire is connected to a switched 12V accessory source and the black wire to a good ground. Check the vehicle's fuse box for any blown fuses related to the accessory circuit.
Cannot find "EASWEL" in Bluetooth device list.	Adapter not powered on. Bluetooth on source device is off or not in pairing mode.	Ensure the vehicle's ignition is on and the adapter is receiving power. Make sure Bluetooth is enabled on your smartphone/device and it is actively scanning. Try restarting both the head unit and your Bluetooth device.
No audio output after pairing.	Incorrect source selected on Alpine head unit. Volume too low. Adapter not fully plugged into head unit.	Ensure the Alpine head unit is set to the correct auxiliary input source (e.g., "AUX", "AI-NET"). Increase the volume on both your paired device and the Alpine head unit. Check that the blue multi-pin connector is fully and securely inserted into the Alpine head unit's auxiliary port. Some Alpine units may require activation of the AUX input in their menu settings. Consult your Alpine head unit manual.
Poor audio quality or intermittent connection.	Interference. Device too far from adapter. Loose connection.	Move your Bluetooth device closer to the adapter. Ensure there are no large metal objects or other electronic devices causing interference. Check all wiring connections for security. Try pairing with a different Bluetooth device to rule out device-specific issues.
Head unit does not recognize the adapter.	Incompatibility with specific Alpine model. Adapter not fully connected.	Double-check that your Alpine head unit model is listed as compatible (IDA-X305, KCE-400BT, CDA-105Ri). Ensure the blue connector is firmly seated in the correct auxiliary input port. Some Alpine units require the "AUX" or "CD Changer" function to be enabled in the head unit's settings menu. Verify that the adapter is receiving power correctly.
