Cellular / Entertainment / Navigation / Audio: 9O-2
Repeat speaker failure can be caused by a damaged
amplifier. Test for a damaged quad bridge output in the
amplifier if the wiring between the amplifier and speaker
test negative for a short to voltage. Prolonged exposure
to DC voltage can cause a speaker coil to short. An early
indication of a shorted speaker coil is distortion/noise
and eventual failure.
Remote Radio Audio Signal Inputs-
Audio output from the OnStar
®
communications module
connects to the remote audio signal inputs of the radio.
When the cellular telephone mute signal goes to 0 volts,
the radio over-rides any other audio signal and uses
these inputs as the source for the output to the speakers.
Cellular Telephone Mute
The OnStar
®
communications module uses the cellular
telephone mute signal circuit to over-ride the radio for
OnStar
®
communication. When cellular telephone mute
is not active, this circuit is held at 1-volt by the radio.
When the cellular telephone mute signal is pulled to
ground, the radio over-rides any other audio signal and
uses the remote audio signals as the source for output to
the speakers. If the radio was OFF when this circuit is
pulled low, the radio will turn ON. Additionally, the radio
fades the speakers to full front, adjusts the volume to an
initial audible level, and sets an Auto Tone designed for
optimal use with OnStar
®
. When the mute signal is no
longer pulled to ground, the radio returns to the mode it
was in previously.
Component Description
Antenna System
The antenna system receives broadcast AM or FM
stereo signals from free space and sends the signals to
the radio receiver for processing via a coaxial antenna
cable. Good antenna grounding is important for good
radio reception.
Radio
The operator interfaces with the radio system through
the radio display and controls. Through these controls
the operator is able to control system power, volume,
fade, balance, bass, and treble equalizations. Control on
the integrated CD, MP3, or XM Satellite Radio system is
also available when equipped with these options. A VFD
(vacuum florescent display) provides system feedback to
the operator.
The radio processes the AM and FM signals from the
antenna system or the information from the CD media,
amplifies that information and sends the output to the
speaker system.
The radio is located in the instrument panel center stack
area and is fastened to the instrument panel by
fasteners. A rear bullet type guide pin is provided to aid
in aligning the radio. An electrical connection to the radio
is a 30-way connector that is part of the I/P harness,
antenna lead connector, and an additional 16-way
harness connector is present on OnStar
®
equipped
vehicles. Additional service length is provided in the
radio harnesses to allow connection prior to radio
installation.
Radio amplifier outputs to the speakers are protected
from damage should speaker leads become shorted to
ground or shorted to vehicle power. The radio will sense
these conditions and shut down the amplifier outputs in a
non-destructive manner. After the short condition is
removed, the radio will return to normal operation.
UVA Radio
The UVA radio is a dual play radio that supports the
playback of CDR, CDR/W and CDROM media with
software decoders for MP3 format.
Auxiliary Jack Socket
The AM/FM Stereo CD radio shall provide a 3.5 mm
Auxiliary stereo jack that will allow playback of audio
signals from remote devices (e.g., portable tape player,
portable CD player or MP3 playback device, etc.).
OnStar
®
OnStar
®
equipped (RPO UE1) vehicles use the radio
amplifier and speaker system for voice communication
from the OnStar
®
operator to the vehicle. Voice
communication from the vehicle to the OnStar
®
operator
is through the OnStar
®
microphone and module, which
is not a part of the radio system.
When OnStar
®
begins operation, the radio volume is set
to a preset level, auto tone preset for OnStar
®
becomes
active and the fade control is adjusted to the full front
speakers. The radio volume control can then be used to
adjust the volume to a desired level.
The radio system and OnStar
®
system are connected
through the 16-way connector at the back of the radio.
Left and right channel OnStar
®
audio, mute control of
radio functions by OnStar
®
and the audio signal ground
are the circuits provided in the 16-way connector.
Disconnecting the 16-way connector from the radio will
isolate the radio system from the OnStar
®
system.
Voice communication from the vehicle to the OnStar
®
operator could be possible under this condition.
However, the vehicle occupant will not be able to hear
the OnStar
®
operator.
For more information regarding radio operation
problems, refer to “Symptoms - Entertainment”
Theft Deterrent
The radio theft deterrent system is intended to disable
radio functionality if incorrect vehicle information is
received by the radio. The radio disables functionality if
the VIN information received by the radio does not
match the VIN information that has been learned by the
radio. A VIN sequence is the last 6 digits of the VIN. The
radio receives this information in a GMLAN frame form.
The radio shall provide the following theft operating
modes as part of the radio theft deterrent system:
• No VIN Mode—A radio that has not received or
learned a VIN. In this mode the radio has limited
functionality.
• Normal Mode—A radio has received a VIN sequence.
The radio only learns the VIN sequence if the VIN
sequence contained all 6 digits. In this mode the radio
has full functionality.
