48 AUX MODE
OVERVIEW
AUX Mode is entered by inserting an AUX device using
a cable with a 3.5 mm audio jack into the AUX port or by
pressing the "Player" button located at the bottom of the
display. Once in Player Mode, press the "Source" button
and select AUX.
Inserting Auxiliary Device
Gently insert the Auxiliary device cable into the AUX
Port. If you insert an Auxiliary device with the ignition
ON and the radio ON, the unit will switch to AUX mode
and begin to play when you insert the device cable.
Controlling The Auxiliary Device
The control of the auxiliary device (e.g., selecting play-
lists, play, fast forward, etc.) cannot be provided by the
radio; use the device controls instead. Adjust the volume
with the ON/OFF VOLUME rotary knob, or with the
volume of the attached device.
NOTE: The vehicle radio unit is acting as the amplifier
for audio output from the Auxiliary device. Therefore if
the volume control on the Auxiliary device is set too low,
there will be insufficient audio signal for the radio unit to
play the music on the device.
