Radio Messages - GMC 2004 Envoy Owner's Manual

TRAF (Traffic): If TRAF appears on the display,
the tuned station broadcasts traffic announcements and
when a traffic announcement comes on the tuned
radio station you will hear it.
If the station does not broadcast traffic announcements,
press the TRAF button and the radio will seek to a
station that does. When a station that broadcasts traffic
announcements is found, the radio will stop seeking
and TRAF will appear on the display. If no station
is found that broadcasts traffic announcements,
NO TRAFFIC will appear on the display.
If TRAF is on the display, press the TRAF button to
turn off the traffic announcements.
The radio will play the traffic announcement even if the
volume is low. The radio will interrupt the play of a
CD if the last tuned station broadcasts traffic
announcements.
This function does not apply to XM™ Satellite Radio
Service.
