Back, Map, More, and Avoid These buttons have common functions across all three Detailed Traffic Event screens. Back: Press to return to the screen used to display the selected detailed traffic event. Map: Press to show the related traffic event on the map. If selected, the Map Traffic Event Icon screen displays. More: Press to display more of the traffic event description, if the whole event does not fit in the given display. Avoid: This button is used to avoid the location of an event on the route. If selected, a new route is calculated and the related traffic event is avoided. After the new route has been calculated, the navigation system goes to the full map screen and shows the new route. Traffic Voice Prompts The traffic voice prompts are part of the current navigation voice prompts. If the navigation voice prompts are turned off, all traffic prompts are also turned off. If the voice prompts are on, whenever an Alert for Approaching Traffic or Alert if Better route Available is displayed, the system gives the related voice prompt. The content of the voice prompt depends on actual traffic event data. The RPT (Repeat) hard key is for navigation traffic maneuvers only. It is not used to repeat traffic prompts. During a traffic voice prompt, if RPT is pressed, the current prompt playback cancels. Map Traffic Event Icon with Back Screen Scroll to the new traffic ICON, and the INFO button displays for that traffic event. Press INFO and the detailed traffic event screen displays. Press the NAV hard key to go back to the Full Map screen. Anything that cancels the Alert for Approaching Traffic, also cancels the related voice prompt. Traffic prompts are disabled during OnStar® or Voice Recognition activity. 2-35
