Functionality check

Connect an iPod unit with stored music.
Check that the adapter controls the iPod unit: "Volvo for life" and "OK to disconnect" appear on the iPod unit display. The scroll wheel and menu buttons of the iPod adapter are locked.
Select "CD changer" using the SOURCE button on the radio.
Check that the iPod unit plays. If it does not have any defined playlists, only CD 10 (playlist 10) will be played.
