The new 911 comes standard with PCM, the central control unit for audio, navigation and communications. The new redesigned PCM system is now even more powerful and multifunctional, yet it’s easier to operate.

You can choose to operate the PCM using the button controls or the 6.5-inch touchscreen. With a maximum of five list items per page, the screen displays information very clearly, and a help function is displayed at the foot of the screen.

The integrated single CD/DVD drive is—in combination with the optional Bose® Surround Sound system—now able to play back music from audio and video DVDs in the 5.1 digital format. A six-disc CD/DVD autochanger integrated in the PCM is available as an option.

The AM/FM radio is also accessed through PCM. It can store up to 48 memory presets.

The optional GPS navigation system now has a hard drive containing map data for most areas, allowing for considerably faster route calculations with a choice of three alternative routes.

A touchscreen enables rapid destination input and instant viewing of points of interest (POIs) by simply allowing you to touch the symbols on the map. The system also supports automatic navigation along a previously recorded route (reverse route navigation), as well as a compass and GPS-based navigation in regions not covered by your navigation DVD.

When viewing a map, it is possible to select between a new bird’seye perspective view and the familiar 2-D display. At highway exits, graphical turn indications are displayed for better orientation. In splitscreen mode, you can choose to display not only the current map overview, but also a list of icons that represent dynamic route guidance.

The optional electronic logbook enables automatic recording of mileage, route distance, time and date, starting point and destination as part of every journey. Once you have downloaded the logbooks from the PCM via Bluetooth® or the optional USB interface, you can evaluate the data on your PC using the software supplied.

Almost all of the functions of PCM can be controlled using the optional voice control system. The menu item is read aloud exactly as it is displayed on the screen and the voice control system recognises commands or sequences of numbers, whoever the speaker. It then gives an audible acknowledgement and carries out the functions you request. Without needing to ‘train’ the system, it is possible to view phone book entries, tune into radio stations and enter navigation destinations directly by speaking whole words, rather than by dictating just one letter at a time.

This high-quality sound system is fitted as standard on all 911 models. A separate amplifier with a total rated output of 235 watts and nine loudspeakers creates the perfect interior sound experience.
