CD Adapter Kits
Although this is not a recommended practice, it is possible
to use a CD adapter kit with your cassette tape player.
The adapter kit cassette should begin playing like a regular
audio cassette tape once inserted. If the cassette
immediately ejects, turn the radio off, turn the ignition on
and press and hold the TAPE AUX button until the tape
icon flashes on the display. Insert the adapter cassette
again. It will power up the radio and begin playing.
This override routine will remain active until EJECT
is pressed.
Playing a Compact Disc in the Single Remote
Disc Player
If you have this option, you can play one compact disc
(CD) at a time.
To load a CD into the player, hold the disc with the label
side up and insert it carefully into the player
(approximately half way). The disc will automatically
be pulled into the player. If the radio is off and the
ignition is on when a CD is inserted, the radio will turn
on and begin playing the CD. It is possible to load and
unload CD's with the ignition off. To load a disc with
the ignition off, press the EJECT button on the remote
player and then insert the disc. To remove the disc, press
the EJECT button and remove the disc from the player.
