Navigation Plus including the BMW Head-Up Display brings together several useful components: a navigation system with built-in 8.8" LCD colour display, radio, MP3 player, RDS double tuner and an instrument cluster with high-resolution 5.7" TFT display. The full-colour BMW Head-Up Display projects relevant driving information directly into the driver's line of vision, allowing him or her to fully concentrate on driving. Route guidance is provided via an arrow and map display, along with spoken instructions. The navigation system is operated intuitively via the iDrive Touch Controller with direct menu control buttons and eight functional bookmarks or – depending on the vehicle's features – via voice control.Navigation Plus shows drivers the quick and direct route through numerous European countries and in some cases even further afield. TMC technology is used for the early detection of traffic obstructions and alternative routes are calculated at rapid speed, for a safe, convenient arrival.
