Functional enhancements of the headunit basic version

Combining several devices that were previously external in one housing has resulted in the following benefits:

• Additional functionality
• Software is easy to extend using suitable interfaces
• Fewer plug-in connections, therefore fewer fault sources
• Optimized installation room and lighter weight

The HU-B has a modular structure. The most important systems for communication are integrated in the HU-B as modules. The HU-B combines the following components in a housing:

• Tuner (FM)
• Tuner (AM)
• Diversity aerial
• DAB tuner (L band and band III)
• IBOC decoder (US only)
• SDARS satellite tuner (US only)
• Audio system controller
• MOST-CAN gateway
• Interface to the Central Information Display (APIX)

The CD drive is suitable for playing CDs (digital audio). Both the MP3, WMA and AAC formats (m3a, m3p from iTunes) are supported.
