GMC 2007 Savana - Manual (Page 195)

Radio Messages
CAL (Calibration): The audio system has been
calibrated for your vehicle from the factory. If
CAL appears on the display it means that the radio
has not been configured properly for your vehicle
and must be returned to the dealer for service.
LOC (Locked): This message is displayed when
the THEFTLOCK
® system has locked up. Take
the vehicle to the dealer for service.
If any error occurs repeatedly or cannot be
corrected, contact your dealer.
Playing a CD
Insert a CD partway into the slot, label side up.
The player pulls it in and the CD should begin
playing. CD appears on the display. If you want to
insert a CD with the ignition off, first press the
eject button or the RCL knob.
If you insert a CD with the radio off and the
ignition on, it starts to play.
If the ignition or radio is turned off, with a CD in the
player, it stays in the player. When the ignition or
radio is turned on, the CD starts playing where it
stopped, if it was the last selected audio source.
As each new track starts to play, the track number
appears on the display.
The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs and
the smaller CDs are loaded in the same manner.
If playing a CD-R, the sound quality may be
reduced due to CD-R quality, the method of
recording, the quality of the music that has been
recorded, and the way the CD-R has been handled.
There may be an increase in skipping, difficulty in
finding tracks, and/or difficulty in loading and
ejecting. If these problems occur, check the bottom
surface of the CD. If the surface of the CD is
damaged, such as cracked, broken, or scratched,
the CD will not play properly. If the surface of the
CD is soiled, see Care of Your CDs on page 226 for
more information.
