The BMW Entry Nav Head Unit (also referred in the document as HU) is a highly integrated hardware
platform with a well defined features set, in 1-DIN format with remote display.
Miscellaneous entertainment functions, like analogue and digital tuners, CD Audio Disks,
MP3/MP4/DiVx from USB, will be combined with a multimodal MMI (voice recognition or haptic
controller based) for vehicle settings, climate, entertainment, etc.
Extensive navigation functions, including 3D Map as well as communication aspects (phone,
telematics, browser, ...) are included.
Interconnection with the Car Network is provided with CAN (high speed) and MOST (25 Mbit/s);
additionally an Ethernet link is present for housekeeping aspects.
A standard MOST/CAN Gateway (UGW) and the complete MOST master functionality are included.
The HU will be build on the Standard BMW Autosar Core 2.1
The conceptual system overview of the MM proposal for the Head Unit is shown in the followingfigure
