Traffic Voice Prompts
The traffic voice prompts are part of
the current navigation voice prompt
settings. The traffic voice prompt
can be turned on and off by
selecting Traffic Voice Prompt in
Voice Prompt on the CONFIG Nav
screen. If the navigation voice
prompts are turned off, all traffic
prompts are also turned off.
If the voice prompts are on and an
Alert for Approaching Traffic
displays, the related voice prompt is
provided.
RPT (Repeat) does not repeat traffic
prompts, only navigation traffic
maneuvers. The current prompt
playback cancels if RPT is pressed
during a traffic voice prompt.
Traffic prompts are disabled during
OnStar® (if equipped) or Voice
Recognition activity.
Alternate Route
When Detour Available displays, a
possible quicker route is available
and an alternate route can be
selected to detour around the traffic
condition. Press Yes and a new
route is calculated. This option is
only available when the multiple car
icon appears.
XM NavTraffic information might
not be provided for the alternate
route, depending on what type of
road the vehicle is traveling on.
