(Navigation system with iDrive and Real Time Traffic Information - convenient functions at your fingertips.
The highly detailed maps now offer a variety of views to help make finding your route even easier. If you want more than the 2-D view, select a night view, a height mode, or even 3-D perspective. You can also add verbal or written instructions. Take advantage of the travel planner, for any trip requiring multiple stop-off points. Up to 30 different locations can be programmed along the same route. By switching from a DVD-based system to a quicker, hard drive-based system, BMW also increased the operation speed
