Radio and CD changer

Introduction

This technical documentation describes the various radios and
CD changers used in the E85.
The following radios are available for the E85:
- BMW radio-CD (basic in EU)
- BMW Business radio-CD (basic in US)
- BMW Business radio-MD (basic in Japan)
- BMW multi-information radio MIR (EU only)
- 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 can no longer be ordered.
