Radio and CD changer: Notes
The following radios are available for the E85:
- BMW Business radio-CD
- BMW central information display radio CID radio
All radios are new generation radios (NG radios). The radios feature a K-bus connection via which they communicate with other control units.
The AF input (audio signals) of the CD changer was increased from 0.5 V to 2.0 V in order to increase the signal-to-noise ratio. The new generation radios detect whether they communicate with a 0.5 V CD changer (old) or a 2.0 V CD changer (new) and switch over the input accordingly.
A 6-CD changer is additionally available for the E85.
A radio with a cassette drive is no longer available.
