The method to turn on the audio on the 2007 Octavia is.

1. Purchase an AUX cable, with 3.5mm audio heads on both ends.

2. Prepare an MP3, copy the songs, and test that the MP3 function is normal before use.

3. Plug one end of the AUX cable into the Octavia's AUX port (in the driver's right hand, inside the center armrest) and the other end into the MP3 player. The MP3 player will be turned on and played.

4. Turn on the FM radio and press the CD button twice. The display will prompt: AUXIN. At this time, the MP3 music comes out.
