GMC 2007 Canyon - Manual (Page 214)

When a station that broadcasts traffic
announcements is found, the radio stops seeking
and TRAF appears on the display. If no station
is found that broadcasts traffic announcements,
NO TRAF appears on the display.
If TRAF is on the display, press the TRAF button
to turn off the traffic announcements.
The radio plays the traffic announcement if the
volume is low. The radio interrupts the play
of a CD if the last tuned station broadcasts traffic
announcements.
This function does not apply to XM™ Satellite
Radio Service.

Playing a CD
Insert a CD partway into the slot, label side up.
The player pulls it in, and READING appears
on the display. The CD should begin playing. If you
want to insert a CD with the ignition off, first
press the eject button or the DISPL knob.
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 to play where it
stopped, if it was the last selected audio source.
When the CD is inserted, the CD symbol appears
on the display. 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.
