Audio connection
The audio outputs of the car kit can be connected to the audio inputs of
the car radio system in several ways. To set the car kit into the mono or
stereo mode depending on the selected installation option, see Set the
mono or stereo mode p. 22.
Select the installation option
To enable the use of the car kit with a car radio system, select one of the

—Stereo output of the car kit
If you cannot connect the stereo output of the car kit to the stereo/
auxiliary input of the car radio (for example, to play music from the car
kit in stereo), select the A1 or A2 option, and set the audio mode to
mono. If the car radio has a mono/phone input, select the A2 option.
Otherwise select the A1 option and use the loudspeaker supplied with
the car kit. If the car radio does not have a mute connector, you can
leave the mute line unconnected. For more information, see Power cable
p. 26.
If you connect the car kit to a stereo/auxiliary input (an aux-in or cd
changer connector) of the car radio, select the B1 or B2 option, and set
the audio mode to stereo. If the car radio has a mono/phone input, you
can select the B2 option to use the car speakers for better audio quality.
If the car radio does not have a mute connector, you can leave the mute
line unconnected. Do not connect the car radio to the mono output of
the car kit. The mono output is designed to be used with a loudspeaker
and does not work properly when connected to a car radio.
If you select an installation option that uses the supplied loudspeaker,
voice calls, ringing tones, and navigation instructions can be heard even
if the car radio is switched off. Instead of using the supplied
loudspeaker, you can connect to the car kit one of the car speakers with
a relay if the impedance of the speaker is at least 4 ohms. In this case,
connect the mute connector to the relay as well. If the impedance is
over 8 ohms, the output power is significantly lower than normally.
Set the mono or stereo mode
Set the car kit to the mono mode (default setting) or the stereo mode
depending on the selected installation option. To switch between the
modes, switch off the car kit if it is on, press the Navi wheel, and within
5 seconds, press and hold
for 10 seconds.
