1. GENERAL DESCRIPTION
This Section describes the cellular phone hands-fr ee kit connec tion incorporated into the m ain wiring harness of all
MY 2003 VY and V2 Series vehicles.
The cellular phone connector is taped back to the m ain wiring harness and is located at the left front of the centre
console f or right- hand drive vehic les . For lef t- hand dr ive vehicles it is located at the r ight f r ont of the c entre c ons ole.
To ac cess the connector , rem oval of the appropriate ins trum ent panel lower extens ion side panel is required, which
is described in this Section. A connection kit is available through an authorised retailer.
The connector provides constant and accessory position battery power outputs and ground connection for the
cellular phone. It also provides the following connections that interface with the radio when a telephone hands-free
kit with the appropriate functions is connected.
RADIO TELEPHONE MUTE
W henever a call is m ade or received, the radio will display VOICE IN and the volume of the radio will be muted or
the CD will be paused. A suitable hands-free cellular phone kit with a mute output function is required to be
connected to pin X1_4 (mute) of the cellular phone connector.
RADIO TELEPHONE INPUT
This function allows the audio from a suitable hands-free cellular telephone kit to be reproduced through the radio
speakers. A suitable hands-free cellular phone kit with mute output and external speaker functions is required and
is connected to pins X1_4 (mute), X1_5 (voice signal) and X1_6 (voice return) of the cellular phone connector.
The phone input has independent tone from the nor mal audio sources. T he bass, treble, fader and balance can be
adjusted to suit the particular phone/preference whenever VOICE IN is displayed on the radio. These settings will
then be used whenever the phone input is activated, and does not interfere with the settings for radio or CD
playback.
With both functions, the radio returns to the previous playing mode and audio settings when the call ends.
IMPORTANT: Before connecting a cellular phone hands-free kit to the vehicle, refer to the relevant installation or
operators manual(s) for the correct installation procedures.
