• No Audio Output:
  • Check all wiring connections, especially power (BATT, ACC-IN, GND) and audio input/output (AU-R-IN, AU-L-IN, AU-GND, SPDIF-Y, SPDIF-Z, SPDIF-GND).
  • Ensure the operating voltage is within the specified +9V to +16V range.
  • Verify that your Android head unit is correctly configured to output L/R stereo audio.
  • Confirm that your vehicle's SPDIF audio amplifier module is functioning correctly.
• Distorted Audio:
  • Check for loose or corroded connections.
