Radio and CD Change

Radio and CD Changer





The radios in the (E83) X3 SAV are identical to those in the (E85) Z4 except for the color of the front finisher panel. The controls and functional efficiency also correspond to those of the (E85) Z4 radio systems.
The (E83) X3 SAV does come with a BMW Business Radio w/CD as Standard.
Additionally available is the BMW Central Information Display CID radio w/ navigation.
All radios are new generation radios (NG radios). The radios feature a Kbus connection via which they communicate with other control units. Radios with a cassette deck are no longer available.
A 6CD changer is also available for the (E83) X3 SAV. The CD changer audio signals have a level of 2.0 V (increased interference voltage distance). New generation radios detect whether they are communicating with a 0.5 V CD changer (old) or a 2.0 V CD changer (new) and switch over the input accordingly.
