Audio Systems: Notes
Two audio sources are offered on the E90. Both are on the MOST bus and have CD playing capabilities.
The base version utilizes a single cd drive and a dual LCD line readout and is referred to as the RAD2 ('Professional' radio). This audio system can be ordered as a HiFi system with 180 Watt capability or upgraded to Top-HiFi Logic7 with 420 Watts of power.
The second audio source is the familiar Car Communication Computer (CCC or Navigation system, Professional). Because the CCC does not have an LCD readout, it utilized the CID as a visual monitor. A vehicle equipped with CCC will always come with the Top-HiFi Logic7 system with 420 Watts of power as standard.
The following new features have been introduced:
- New 'Professional' radio with MOST capabilities (RAD2 and CCC)
- Additional audio input for external devices
- Playback of MP3 files (RAD2 Directly / CCC with CD Changer)
