Besides the new menu display, the route guidance graphics and the map views within the navigation function have also been modified and improved by the addition of various interactive options. The split-screen portion of the central information display, for example, now includes new display functions for the navigation mode.
While the driver is still entering the destination by selecting the country, city and street, the chosen destination additionally appears in the map view on the split screen for easier orientation. If necessary, the driver can use a zoom function to change the section of map shown and check that the selected destination is the intended one.
High Guiding and 3D City Models.
For the purposes of actual route guidance, the familiar guiding function using arrows in the split screen has now been supplemented by a High Guiding variant, which clearly flashes up detailed navigation information in the multifunctional instrument cluster display, the central information display as well as the Head-Up Display.
High Guiding is automatically activated when the vehicle comes within a certain range of the next navigation instruction: from a distance of 300 metres outside built-up areas and 150 metres in built-up areas, the reduced arrow display switches to a detailed bird’s-eye perspective of the surrounding area.
The driver furthermore receives precise directions for changing lane at the right time. As the driver draws closer to the event, the display gradually shifts from the bird’s-eye map view to an overhead view of the traffic situation for optimum orientation and guidance. A dynamic display of the vehicle’s present position calculated in real time serves as an aid that allows drivers to closely track their progress throughout the turn-off phase.
The new navigation view option “3D City Models” features a realistic depiction of surrounding streets and buildings to help drivers get their bearings, provided such a visualisation of the city in question is stored in the vehicle’s database.
The extended toolbar – putting extra functions at the driver’s fingertips.
In navigation mode, there is now an extended toolbar that, for the first time, allows the map contents to be customised quickly and easily without having to exit from the map view. The desired change takes effect immediately, and the driver is able to effortlessly switch the view to suit the current situation and the information required.
The moment the driver selects the icon for the extended toolbar with the iDrive Controller, a second toolbar appears as an extension of the original icon bar. This can then be used to open additional selection options in the same view, which were previously only accessible via Option menus.
The settings here allow the user to call up Real-Time Traffic Information (RTTI) or weather information, for instance, to display POIs, or quickly switch from the overhead map view to the bird’s-eye view. Depending on the data required, drivers are therefore able to activate individual features, quickly find the necessary information, and then return to their preferred map view.
Interactive map and PIE menu.
The new BMW Navigation system Professional also adds several new functions to the interactive map view. The iDrive Controller can now be simply turned to alter the map scale or tilted to move the section of map in the display, even in a diagonal direction. Another new feature of the interactive map view is the ability to call up special functions directly from the map itself.
All the driver has to do is select a point on the interactive map and the PIE menu will open up in front of the map, providing quick and easy access to a wide range of actions. Depending on the information stored, the driver just has to click to show points of interest in the vicinity, view details for them (where available), start navigation to them, change the map view or display the current location or destination.
And should any additional data be available for the selected location, such as a telephone number, website details or an email address, the driver can retrieve this information with a click too, then visit the homepage, for example, or write an email. The real beauty here lies in the system’s straightforward, intuitive and quick operation.
RTTI – Real Time Traffic Information.
The latest generation of the BMW Navigation system Professional once again employs RTTI technology for calculating routes and diversions accurately and reliably by factoring in the real-time traffic situation for both route guidance and calculation of the arrival time. By using the 3G mobile network and the vehicle’s built-in SIM card, RTTI offers the benefit of faster data transmission combined with more extensive coverage. What’s more, the new system extends beyond motorways and major highways to cover country roads and even a large number of urban routes as well.
