NG Radios
Introduction
Starting September 2000, a family of new generation radios will begin to be phased into
production. The exception to this is the E52 which has been available with the MIR (multi-
information radio) NG radio since series launch in mid 2000.
The NG “New Generation” radios will have increased functions:
Radio can be operated without KL R.
Radios are world frequency.
Car memory programming.
Audio mixing on vehicles equipped with navigation.
The radios external appearance has not changed. NG radios can be identified by their “53”
designation.

NG Radios
Reset and Voltage Monitoring
A radio reset is triggered by under voltage or the internal processor monitor. The reset
function restarts the radio, similar to turning it off and back on again. Operating voltage is
measured at the KL 30 input. The radio is switched off if the system voltage exceeds 17V
to protect the radio, it will switch on when the voltage falls below 16V.
GAL (Speed Dependent Volume)
The speed signal from the IKE/KOMBI is available to the radio over the K/I Bus. GAL is not
a feature on vehicles equipped with DSP.
Bus Communication
The radio communicates with other modules via the K bus or I Bus dependent on the
model. The information shared over the bus line includes:
IKE/KOMBI - Terminal status (KL 15, KL R)
LCM/LSZ- Lights on
IKE/KOMBI link to TXD- Diagnosis
MID or BMBT- button or rotary knob status.
GM- Key used to lock or unlock vehicle
MFL- audio controls status
NG radios do not use anti-theft codes. Operation of the radio is only possible if
connected to a bus line and the detection of at least one other component.
Multi Information Radio (MIR)
The Multi-Information Radio (MIR) is used in the E52 Z8 and is the first of the NG series of
radios. The MIR contains the radio receiver, display screen, and control panel all in one unit.
A cassette player is not included.
The MIR is used to control and display the:
GPS-Navigation System
Audio system including CD Changer
Telephone
Outside temperature
