  1. Digital Media Changer doesn't work after installation. Please check whether the wire harness is correctly connected. And if there is GND wire(for some car models), please check whether it connects well with metal parts of car radio.
  2. After installation, I pressed CD button for switch, it can switch to MP3 playback status, but only one CD folder works, how should I do? This problem is probably caused by improper folder structure you saved/organised in USB device/SD card. Please follow the rules as abovestated, to access the music, it is important that the music has been saved/organised into folders which are named CD01, CD02, CD03...CD99. Otherwise, all tracks/songs will be recognized as only one virtual CD disk.
  3. When auxiliary audio device is connected via AUX IN slot, I can still hear music sound from USB device, how to do with this?Please then remove the USB device/SD card from Digital Media Changer before you use the AUX IN, otherwise USB device/SD card playback will not automatically stop.

  As to part of the cars equipped with existing CD Changer, we can offer Parallel Harness, which allows Digital Media Changer to hook up with the existing cd Changer. There is a Switch for CDC and MP3 conversion, thus you could choose to play Digital Media Changer or CD Changer as you like. However, please note Parallel Harness is not available for all cars.
  6. My car original stereo has only Cassette, can I connect Digital Media Changer to my car stereo?
  It depends on whether there is extra CD changer port for Digital Media Changer, but has nothing to do with whether the head unit is CD or Cassette.

  The sound from the stereo will automatically mute and the phones ring will be heard over the factory radio speakers.
