Pioneer MVH-S320BT Operation Manual page 44

The microphone should be placed directly
in front of the driver at a suitable distance to
pick up their voice clearly.
AcAUTION
It is extremely dangerous to allow the
microphone lead to become wound around
the steering column or shift lever. Be sure to
install the microphone in such a way that it
will not obstruct driving. It is recommended
to use the clamps (sold separately) to
arrange the lead.
NOTE
Depending on the vehicle model, the
microphone cable length may be too
short when you mount the microphone
on the sun visor. In such cases, install the
microphone on the steering column.
To install on the sun visor
1 Fit the microphone lead into the
groove.
