7. If the system does not initialize within 10 minutes,
the screen below appears. The system is still
initializing but will not automatically exit when the
initialization is complete. Do not immediately follow
the instructions on the screen. After 30 minutes, try
restarting the vehicle to see if the navigation
system completed the initialization. If it did not,
follow the instructions on the screen.
Something is interfering with the system's ability to
acquire its location. Check the following:
* The vehicle must be in an open area with a clear
view of the sky.
* Remove sources of GPS interference like metallic
window tint above antenna, or electrical items
near antenna (see owner's manual for details).
* Check GPS antenna cable connection.
* Restart the engine and repeat the GPS acquire
procedure. If the problem persists, see your dealer.
NOTE: The initialization screen may appear after
battery voltage to the navigation control unit has
been disconnected for more than 5 minutes. If this
happens, follow the on-screen instructions. If you
are still unable to obtain GPS initialization, refer to
the service manual for diagnostic information.
8. When initialization is complete, the disclaimer
screen appears. Select OK.
NOTE: Do not enter a destination yet. For the
navigation system to calculate a route, it must align
the current location to a mapped road (map
matching). This happens when you start driving.
9. Drive the vehicle at least a half-mile from your
dealership, and find a safe place to park. Then set
the map scale to 1/20 by turning the interface dial
clockwise.
• Make sure the VP (vehicle position) 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 does not
"dog track" or spin.
• Make sure the VP icon smoothly follows the
vehicle's maneuvers as you make turns.
• After driving a few hundred feet on a road that is
displayed on the map, the name of the road you
are driving on should appear across the bottom
of the screen.
NOTE: Refer to the service manual symptom
troubleshooting section if the navigation system
fails to map-match after driving the vehicle for more
than a couple of miles on a displayed road.
10. With the map screen displayed, press and release
the NAVI TALK button.
11. When you hear the beep, say "Find the nearest
Acura dealer." The system should display a list of
Acura dealers.

12. Turn the interface dial to highlight your dealership,
then push in on the DIAL/ENTER button.
13. On the Calculate Route to screen, select OK.
14. The system then calculates a route and displays it
as a blue line. If you are in a rural area with
unverified roads, you may see a blue vector line
pointing in the direction of your destination or a
blue/pink dotted line.
15. Follow the voice guidance back to your dealership.
The voice guidance should work even with the
audio system turned off.
16. With the map screen displayed, check the system
interaction with the audio system and the upper
display. Press and release the NAVI TALK button.
After the beep, say "XM channel 125." The upper
display should change to XM channel 125 and
show the Weather Channel.
17. With the map screen displayed, check the system
interaction with the climate control system. Turn on
the climate control system by selecting AUTO.
Then press and release the NAVI TALK button.
After the beep, say "Temperature 68 degrees." The
upper display should change to 68 degrees.
18. The time shown in the upper display should be
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. Go to
Clock Adjustment in the Setup screen, and set
Auto Daylight to ON.
NOTE: If your dealership is located near a time
zone boundary, set Auto Time Zone by GPS to
OFF. The clock then keeps the "home" time if the
client routinely drives across the time zone
boundary.
19. If your dealership is located in a metropolitan area
that has traffic incident or traffic flow data available
(see ACURALINK REAL-TIME TRAFFIC
INFORMATION), do this:
• Select one of the traffic map scales (1/2, 1, 2, or
5 mile scales) by rotating the dial.
• Use the interface dial to scroll to the downtown
area of your city. Freeways and other main roads
should show traffic flow data as red, orange, or
green lines for traffic flow in one or both
directions on the road.
• Small diamond-shaped "traffic incident" icons
may be shown. If so, scroll over an icon and
press in the interface DIAL/ENTER button to see
the details.
• Partially displayed traffic data does not indicate 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 it is
not displaying on the screen, refer to the
Navigation section of the service manual for
more information.
