Infotainment System 7-77 Database Coverage Explanations Coverage areas vary with respect to the level of map detail available for any given area. Some areas feature greater levels of detail than others. If this happens, it does not mean there is a problem with the system. As the map data is updated, more detail can become available for areas which previously had limited detail. See Ordering Map DVDs on page 7‑76 for more information. Voice Recognition The navigation system's voice recognition allows for hands-free operation of the navigation system and the audio system features. Voice recognition only works if the map database is installed in the system. If the radio is off, the only commands would be Hands Free and Help. Navigation voice commands are not available until the I Agree button has been selected. Voice recognition can be used when the vehicle is on or when Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 9‑22 for more information. Using Voice Recognition 1. Press and release the b g steering wheel button. The audio system mutes, and a beep is heard. A voice prompt stating, "Please start speaking after the beep" might be heard. If there is no beep, make sure that the voice volume setting is not turned down. See Configure Menu on page 7‑66 for more information. While voice recognition is active, the system displays a g symbol. 2. Clearly speak one of the commands listed later in this section.
