Handsfree operation

The telephone transmitter and receiver R36 sends
the signals for handsfree operation (Voice, Phone
Mute, etc.) via the MOST Infotainment bus to the
relevant sound system, which is either integrated
into the control unit for front information J533 or
the independent digital sound system control
unit J525. Here, the digital data is converted into
analogue data and is output on the loudspeaker.

Echo and noise compensation

The telephone transmitter and receiver R36 is fitted
as standard with a DSP-based echo compensation
system. If the optional voice operating system is
also ordered, the echo and noise compensation
function of the control unit for voice input J507 is
used. Among other things, this results in an
improved handsfree quality, even for the passenger.
