How to Upgrade the BMW 330 Navigation System

1. Email or call your BMW dealer. Ask them to provide you with the latest BMW navigation DVD. There is a charge for the disk.
2. Upon the DVD's arrival, go to your 330 sedan and find the 'Eject' button on the in-dash navigation device's face. Press this button.
3. The DVD currently being used by the navigation device will eject. Take it out and slide in the latest DVD. Your maps have now been upgraded with the latest version.
