iDrive.

Right to continue, left for back and press to select: you've now learned how to operate the new iDrive which gives you full control over all of the BMW 5 Series Sedan's functions from the navigation system to the integrated user guide.

You can access the most important functions, such as the navigation system, telephone and music system, using the direct buttons. Favorite keys are also available for you to save settings such as radio stations, destinations and telephone numbers. The standard 7-inch Control Display displays all the information you need clearly and in high-quality color. With the navigation system, which comes standard in the 550i, the display increases to 10.2 inches. You can use the "Back" key at any time to retrace your steps.
