NAVIGATION SYSTEM CONTROLS
Screen - All selections and instructions are displayed on the screen. This touch-screen display uses infrared beams that are interrupted by your finger to determine what selection has been made. Because of this, you do not need to push on the screen; all you do is touch your selection. If the system doesn't accept your selection (nothing happens), try moving your finger slightly on the selection; do not push against the screen. You can also use the joystick or the voice control system to make a selection.
MENU button - Press this button to change the display from the current screen to the Main menu. When en-route to a destination, press this button to change routing parameters.
MAP/GUIDE button - Press this button to display a map of your current position for casual driving. When en-route, press this button to switch between the map and route information.
A/C-INFO button - Press this button to display the menu for selecting Setup, Trip Computer (MDX only), Voice Command Help, Calendar, Calculator, and the semiautomatic operation controls for the climate control system.
CANCEL button - Press this button to return to the previous screen.
ZOOM button - Press this button to change the scale when displaying a map. ZOOM Down Arrow allows you to zoom out to see a larger area and ZOOM Up Arrow allows you to zoom in for greater detail. When a list is displayed, ZOOM Up Arrow and ZOOM Down Arrow can be used to page up or page down.
Joystick - The joystick moves left, right, up, and down. Use it to highlight menu selections, scroll through lists, or look around in maps. After making a selection in a menu or list, choose the selection by pushing in on the joystick. You can also choose a selection by touching it on the screen, and in most instances, you can use the voice control system to make a selection.
VOICE CONTROL SYSTEM OPERATION
The navigation system features a highly sophisticated voice control system. This system uses voice recognition to permit hands-free operation of most of the navigation functions.
The voice control system consists of the Talk and BACK buttons on the steering wheel, and a microphone on the ceiling. The audio speakers are used to give voice guidance and voice control feedback.
When the navigation system is giving guidance instructions, the front and rear speakers are muted on the MDX, while only the front speakers are muted on the 3.5RL. When using the voice control system (by pressing the Talk or BACK buttons), the front and rear speakers are muted on both the MDX and the 3.5RL.
NOTE:
When using OnStar on the 3.5RL, the voice control system cannot be used.
Talk button - Press this button to activate the voice control system to accept voice commands.
*BACK button - This button has the same function as the CANCEL button. Press this button to return to the previous display. When the previous display appears, the system prompts you to give a command and sounds a beep. Press the Talk button to issue your next command.*
Microphone - Receives voice commands and transmits them to the navigation unit for interpretation.
Using the Voice Control System
The voice control system is activated with the Talk button. To control the navigation system by voice, press and release the Talk button, then pause a moment before you give a voice command. Once the voice control system understands your command, it updates the navigation system, and may prompt you for additional commands, depending on the next screen.
NOTE:
To view a complete list of the voice commands, refer to the Navigation System Manual, or press the A/C-INFO button and select Voice Command Help.
Improving Recognition
To achieve optimum voice recognition, the following guidelines should be followed:
^ Make sure the correct screen is displayed for the voice command you are giving. Refer to the Navigation System Owner's Manual.
^ Close the windows and the moonroof.
^ Set the fan speed to low (1 or 2).
^ Adjust the air flow from the vents so that it does not blow against the microphone on the ceiling.
^ After pressing the Talk button, wait for the beep, then give a voice command.
^ Give a voice command clearly in a natural speaking voice without pausing between words.
NOTE:
^ If the system cannot recognize your voice command, speak louder.
^ If the microphone picks up voices other than yours, the system may misinterpret your voice commands.
^ If you speak a command with something in your mouth, or with a heavy accent, the system may misinterpret your voice commands.
NAVIGATION SYSTEM OPERATION
Selecting a Destination
A destination can be selected by Address, Intersection, Place, Personal Address, Previous Destination, Map Input, or Today's Destinations using the touch-screen, the joystick, or the voice control system. Refer to the Navigation System Manual for detailed information.
Traveling to a Destination
Confirm a selected route - The system display asks you to select one of the following route options:
^ Direct Route - Takes the least amount of time
^ Easy Route - Minimizes the number of turns
^ Minimize Freeways - Avoids freeway travel (when possible)
^ Minimize Toll Roads - Avoids toll roads (when possible)
^ Maximize Freeways - Incorporates freeway travel (when possible)
*Going off the route - If you leave the route, the system recalculates the route from your current position, and displays a new highlighted route.*
Modifying the route - The system can recalculate portions of the route and/or avoid a specific street, and then return you to the current route.
Save current location - This option stores the current location for later use (it does not change or cancel the route instructions currently in progress). A location can be stored any time the navigation system is in use.
*Off-road tracking - This option displays small circular dots ("bread crumbs") on the map if you drive on a road not shown on the navigation screen. These bread crumbs begin to appear approximately 1/2 mile away from a mapped road, and allow you to retrace your route back to a mapped road. They will not appear if this feature is turned off during setup.*
Personal Addresses
Two users can each store up to 100 destinations (addresses with phone numbers) in the system. A PIN (Personal Identification Number) is optional. Refer to the Navigation System Manual for instructions on how to enter a PIN and use Personal Addresses.
Go Home
This option allows a single button entry to set your home address as a destination. A PIN is optional.
System Limitations
Always verify the audio and visual route information by carefully observing roadway signs, signals, etc. Use your own good judgment, and obey traffic laws while driving. The navigation system has these limitations:
^ The GPS (global positioning system) satellites used by the navigation system are operated by the U.S. Department of Defense. For security reasons, certain inaccuracies are built into the GPS. This can cause occasional positioning errors of up to several hundred feet. If the navigation system indicates your position incorrectly, wait several seconds until it corrects itself. The system may also correct itself after you make a turn or cross a road.
^ The routes calculated by the system may not always be what you consider to be the most direct ones. Try different routing methods to obtain the best route. Even the direction your vehicle is pointing influences the route calculation.
^ Since businesses fail or move to new locations, some information may be inaccurate. Also, route guidance may conflict with actual road conditions such as street closures, construction, and detours.
^ Occasionally, the navigation system may "reboot" due to excess heat or shock, or from recalculating a route too many times. Rebooting does not necessarily indicate a need for service.
^ GPS reception is affected by outside electrical interference from aftermarket electronic devices placed near the GPS antenna or navigation unit. Aftermarket metallic tinting of windows above the GPS antenna can seriously degrade the GPS signal.
MAP COVERAGE AREAS
The map database is stored on a Digital Versatile Disc (DVD) located in the navigation control unit. The database covers the 45 contiguous U.S. states and parts of Canada.
Map Types
The maps that you view on the screen consist of two types of roads: "verified roads" and "unverified roads." Verified roads have been driven by the database vendor. Information about the road's average speed, turn restrictions, or whether it is a one-way street are contained in the navigation system. Roads within metropolitan areas (detailed coverage), interstate freeways, and major roads connecting cities are typically "Verified." They can be recognized on the screen (daytime setting) as the darker colored roads.
*Unverified roads may be found in rural areas. The information about these roads may have inaccuracies. Therefore, they are shown for reference only. They can be recognized on the screen (daytime setting) as a light brown color.*
*Guidance in unverified areas depends on the setting for "Unverified routing" made during setup. If the setting is OFF, then you will see a dotted blue vector line pointing to your destination when driving in an unverified area. You will have to manually choose roads from the map to get to your destination. If the setting is ON, then you will see a blue/pink route line and receive route guidance. Pop-up cautionary boxes appear while on route to alert you when entering unverified areas.*
*NOTE:
This feature is set to OFF from the factory.*
Detailed Coverage
Many cities and metropolitan areas are fully mapped. Detailed map coverage is shown.
Non-Detailed Coverage
*Cities and towns in the non-detailed map coverage area may have incomplete mapping. Only major federal, state, and county roads leading to and through these cities and towns are mapped. These "verified" roads are shown in black. All other streets are "unverified," and are shown in light brown. If you see an asterisk (*) next to the city name,
^ Streets may be missing completely, or shown in the wrong location.
^ Street address information may be unavailable, and you may be prompted to use the map to locate your destination.
^ Streets may be either named incorrectly, or have no name ("unnamed road").*
*Guidance in unverified areas depends on the setting for "Unverified routing" made during setup. See "Driving to your destination" in the Navigation System Manual for more information.*
NAVIGATION SYSTEM SETUP AT TQI
The navigation system must be allowed to initialize itself before use. During initialization, the system obtains the orbital information of the GPS satellites. When initialization is complete, the system can "locate" itself and function normally. To initialize the system, follow this procedure.
1. Perform the normal TQI of the vehicle, including the audio system. The navigation system voice will not function if the anti-theft code for the audio system has not been entered.
2. Start the engine, and move the vehicle outside, away from buildings and power lines. Then enter the security code for the navigation system. The code is on the Navigation Anti-Theft Code card.
NOTE:
If the Anti-Theft Code card is lost, you can find the code with the Interactive Network (iN) by using the Anti-Theft Code option and the serial number of the navigation control unit. If the card with the serial number cannot be located, you can obtain the serial number from the bottom of the navigation control unit, or you can obtain it from one of the Diagnostic menu screens (refer to the service manual). If you cannot find the code with iN, contact the Automobile Warranty Department at 310-753-3240.
3. The following instructions appear on the screen to indicate the system is initializing. Follow the on-screen instructions.
*NOTE:
The average initialization takes about 10 minutes, but it can take as long as 45 minutes. When initialization is complete, the system proceeds to the globe screen.*
4. *If the system does not initialize, a second screen appears. When this screen is displayed, the system is still performing the initialization. The system does not automatically exit to the globe screen when initialization is complete. After 30 minutes, try restarting the vehicle to see if the navigation system completed the initialization. If not, follow the instructions on the screen.*
NOTE:
The initialization screen may appear after battery voltage to the navigation control unit has been disconnected for more than 5 minutes. If this occurs, follow the on-screen instructions. If you are still unable to obtain GPS initialization, refer to the service manual for diagnostic information.
5. When initialization is complete, the disclaimer screen appears. Touch "OK."
NOTE:
Do not enter a destination yet. In order for the navigation system to calculate a route, it must align the current location to a mapped road (map matching). This will occur when you start driving.
6. Drive the vehicle at least a half mile from your dealership, then find a safe place to park.
7. Press the MENU button.
8. From the "Enter destination by:" menu, select "Places."
9. From the "Find place by:" menu, select "Category."
10. From the "Choose a category:" menu, select "Auto Service."
11. From the "Sub-category:" menu, select "Acura Dealer."
12. From the "Choose one of the following:" menu, select "Sort by Distance to Travel."
13. Select your dealership from the screen listings, then select "OK" on the next screen.
NOTE:
If your dealer location is not correct or needs to be changed, report it to your District Parts and Service Manager (DPSM).
14. If your dealership is in a detailed coverage area, the map will show a blue highlighted route. Follow the voice guidance back to the dealership. If your dealership is not in a detailed coverage area, you may see a blue dotted "Vector line" pointing to your dealership instead of the blue highlighted route. Exercise caution, and use the map to guide you back.
15. While viewing a map, verify that the voice control system is working properly by pushing the Talk button and saying a command, such as "Display 1/2 mile scale" or "Display 1/8 mile scale".
16. Press the AC-INFO button, then select Setup, or use the voice control system and say "Setup". Then verify these settings by touch or with the joystick:
^ *Volume set to the midrange (setup screen # 1)
^ *Display set to AUTO (setup screen # 1)
^ *Voice feedback set to ON (setup screen # 3)
^ *Unverified routing set to OFF (setup screen # 4)*
17. In setup screen # 2, touch "Delete Previous Destinations" to bring up the "Select item to delete:" menu. Select and delete any previous destinations except your dealership.
18. *In setup screen # 4, touch "Time Zone/Clock" to adjust the clock to the correct time. This time is used only for the voice command "What time is it?" It does not set the time on the radio.*
NOTE:
^ If you live in a state or part of a state (like AZ or IN) that does not observe Daylight Savings time, then set the "Auto Daylight Savings Time" setting to OFF.
^ If the dealership is located very near a time zone boundary, then set the "Auto Time Zone by GPS" to OFF. This will allow the vehicle clock to retain the same time if the customer routinely travels back and forth across the time zone boundary.
19. MDX only:
^ Press the AC-INFO button, and select the Trip Computer. Make sure the "Reset with refuel: option is set to ON.
^ Refuel the vehicle, then go back to the Trip Computer and verify that Avg., E/T, and Trip displays have reset.
^ Touch "Previous" to display the previous Trip History screen.
NOTE:
The history button only becomes operational after the OK prompt is touched on the disclaimer screen.
20. *The system contains software for both the U.S. and Canada. When delivered, the system should be set up for the U.S. If the navigation disclaimer screen has an "OK" and a "language" button, then the system is not set up properly for U.S. customers. To correct the setup, do this:
^ Enter the Diagnostic mode using the procedure in the service manual.
^ Select "Navi System."
^ Ensure that the "Navi ECU" portion of the diagram reads, "Navi.ECU for U.S."
^ If it reads, "Navi ECU for Canada," touch the "Chng U.S." button, and then exit the Diagnostic mode.*
21. Return to the Main menu, then clean the screen with a soft damp cloth. You may use a mild cleaner intended for eyeglasses or computer screens. Harsher chemicals may damage the screen.
NOTE:
Do not use shop towels, paper towels, or tissues; they can scratch or damage the screen.
