Transfer audio through a cassette deck. Three cord positions.

1. Check to see if cord is in correct position (side or front entry). 2. If necessary, reposition cord in desired position. 3. Insert adapter with the indicated side up as if it were an ordinary cassette. 4. Turn on MP3 player and adjust volume. 5. Eject the adapter as you would any ordinary cassette. Important Note for Cassette Players with Auto Reverse Function: If your cassette player is in the auto reverse mode, the adapter head and cassette player head may not line up properly resulting in sound distortion or loss of sound. To remedy this situation depress the auto reverse button on your cassette deck. Remove two large screws with coin or screwdriver to reposition cord. Move cord to desired position.

Not recommended for use with vehicles with AC Delco radios.
