If a telephone system with hands-free unit is installed in the
vehicle, the telephone conversation can be conducted via the
car radio system. As such, there is no need to install an addi-
tional loudspeaker. However, the signal leads (AF – Telepho-
ne input and Earth – Telephone input) must be connected to
the car radio (see page 136).
