When installing the handsfree unit, ensure that the cables for the
microphone and loudspeaker will reach the places you intend to mount
Take care not to mount the handsfree unit inside a closed metal housing
or in a place in the car where it would be shielded from radio waves as
this may impair the use of the Bluetooth feature.
To mount the unit, first attach the mounting plate supplied with the
Advanced Car Kit and then secure the handsfree unit using the screw
that goes through the unit. Finally, insert the cover imprinted with the
Nokia logo into the recess and press it into place.
