1, use the data line. Insert the connecting data cable into the USB interface of the in-vehicle system, and connect the other end to the Sony lossless player to play the song files of the Sony player.

2. Use a double-ended audio cable. Plug one end of the audio cable into the Sony lossless player interface, and the other end into the AUX interface built in the vehicle system, and then turn on Sony to play music to connect.
