How to Play a DVD in a 2004 Mercedes
1. Insert the DVD to play into the slot on the dashboard DVD player and navigation system. Wait for the DVD menu to appear on the screen.
2. Follow the prompts and choose whether you wish the DVD to be played on the right-hand rear passenger screen, the left-hand rear passenger screen or both. Touch the selection on the screen until the one you prefer is highlighted, then remove your finger from the screen.
3. Choose to allow the passengers' touch-screen controls so they can work the player from their screens. Touch that option on the dashboard touch-screen to highlight it.
4. Press 'Play' when the DVD menu appears.
5. Adjust the volume settings for minimum and maximum on the dashboard touch-screen panel. This sets a volume range so the passengers in back can adjust the volume without it becoming too loud for you.
