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.
