3.7. Drive the vehicle at least a half-mile from your dealership, and find a safe place to park. Then, zoom in using the
interface dial, and set the map scale to 1/20.
Make sure the vehicle position (VP) icon moves smoothly as you drive and does not jerk from one point to
another. Also, make sure the icon points in the direction the vehicle is traveling; it should not dog track or spin.
After driving a few hundred feet, you should see the name of the road you are driving on at the bottom of the
screen. The system is now map-matched.
NOTE
If the system fails to map-match after driving for more than a couple of miles on a displayed road, see the
symptom troubleshooting in the service information.
3.8. With the map screen shown, press and release the Talk button. You will hear the voice portal prompt followed by a
beep. After the beep, say "Navigation."
3.9. After your command is accepted, wait for the beep and say "Find nearest Acura dealer."
3.10. After your command is accepted, wait for the beep and say the number of your dealership in the list of nearest
dealers.
3.11. After your command is accepted, wait for the beep and say "Set as destination."
3.12. Follow the voice guidance back to your dealership. It should work even with the audio system turned off.
3.13. Make sure the time shown in the navigation display is correct; the system gets it from the GPS satellites. For
areas that do not follow daylight saving time, you may have to adjust the time settings. Select Settings, Clock
Adjustment , and set Auto Daylight to OFF.
NOTE
If your dealership is near a time zone boundary, set Auto Time Zone to OFF. The clock then keeps the home time
zone if the client routinely drives across the time zone boundary.
3.14. Press the Day/Night button to make sure the display switches to the Day, Night, and OFF modes.
3.15. If your dealership is in an area that has traffic incident or traffic flow data available , do this:
Select the map scale icon, then select between the 1/20- to 5-mile scales using the interface dial.
Scroll and center on the downtown area of your city. If your metro area has traffic flow data, freeways and
other main roads should show this data as red, yellow, or green lines in one or both directions.
You may see small, diamond-shaped traffic incident icons. If so, scroll over the icon and select it to see
the details.
Partially shown traffic data does not mean there is a problem with the navigation system. Traffic flow and
density varies from day to day and from one road to another. If your area has traffic, but you cannot see it on
the screen, do a search in the service information using keyword TRAFFIC.
3.16. Clear any information that was saved during the TQI.
Turn the ignition to ACCESSORY.
Turn on the audio-navigation unit.
Press and hold the INFO, SETTINGS, and BACK buttons at the same time until the Select Diagnosis Items
screen appears. Then, release the buttons.
Select Detail Information & Setting, Functional Setup, then All Clear. A confirmation screen appears.
Select Yes. A second confirmation screen appears.
Select Yes. The system resets.
