1. Power On: Turn on your vehicle's ignition and the MMI 2G system.
2. Select AUX Input: Navigate through your MMI 2G menu to select the auxiliary audio input. This option may be labeled as "AUX," "External Source," or similar, often found under the "Media" or "CD Changer" menu.
3. Connect Audio Device: Plug your external audio device (smartphone, tablet, MP3 player) into the 3.5mm AUX-in jack.

6. Maintenance

The KUFATEC MMI 2G AUX IN Upgrade Kit is designed for maintenance-free operation. However, following these simple guidelines can help ensure its longevity:

7. Troubleshooting

If you encounter issues with your KUFATEC MMI 2G AUX IN Upgrade Kit, refer to the following troubleshooting guide:

• No Audio Output:
  • Ensure the MMI 2G system is set to the correct AUX input source.

  • Check all cable connections, ensuring they are securely plugged into both the interface module and the MMI 2G unit.
  • Try a different 3.5mm audio cable.
  • Test with a different external audio device.
• Poor Audio Quality (Static, Distortion, Low Volume):
  • Adjust the volume levels on both your external audio device and the MMI 2G system. Avoid setting either to maximum, which can cause distortion.
  • Ensure the 3.5mm audio cable is fully inserted and not damaged.
  • Check for potential electromagnetic interference from other electronic devices in the vehicle.
  • Ensure the ground connection for the interface module is secure (if applicable to your installation).
• MMI 2G Does Not Recognize AUX Input:
  • Double-check all connections to the MMI 2G unit.
  • Ensure the MMI 2G system has been properly coded or configured to recognize the external audio input (this may require diagnostic tools, consult a professional).
  • Verify that the kit is compatible with your specific MMI 2G version.

If these steps do not resolve the issue, please contact KUFATEC customer support or your installer for further assistance.
