      In 3D Auto Zoom mode, only major thoroughfares are shown. Change to 2D mode and manually adjust the zoom level to see more labeled streets.

      Press Menu, then Route Menu and then select Clear Route. Alternatively, use the New Route feature to create a new route; the old route will be cleared from the display automatically.

      First, check the name of the city. Occasionally the city or town is known by a different name than what you have been provided. Also, in rare cases, some house numbers or streets may not be listed in which case you may find an address that is on the same street. Finally, you can change the route to locate the nearest intersection, or nearest town instead.

      House numbers are estimated positions within the block. Typically the GPS will put you within a few feet of the actual position.

      The WorldNav does not require maps to be transferred. All maps and POIs are already preloaded onto your device. To be informed of future updates please register at www.teletype.com/register.

      The Quickest Route setting will choose the fastest route, regardless of mileage or distance. The Shortest Route setting will choose the route with the shortest distance, regardless of speed. Freeways will create a route that favors highways. Truck Emergency will disregard all restrictions except low bridges. Truck Via My Points allows you to create a route through selected My Points. (See following FAQ)

      First you need to create a My Point, which is essentially a “favorite” location. While in Map Mode, press the red target in the center of the screen and select Mark. This will save that location. You can save an unlimited number of My Points. To route through a My Point, select “Truck Via My Points” in your Route Settings. Refer to the WorldNav software user guide for details.

      Yes, advanced users can substitute other .wav files for any of the warning sounds found in the TTWorldNavigator Sounds folder such as reroute, spdBeep sounds. Rename the .wav file to correspond to the original file name to replace the existing file with the new file. Transfer the file using your laptop or desktop PC.

      Press Menu then use the right arrow icons to scroll to the third screen and then press Language. Select your preferred language and press OK. Notice that the menus will also change to the corresponding language. (Language choices are available in Premium and Truck Editions only.)

      Some WorldNav devices allow you to select "system" languages. This choice applies only to the hardware operation of the device rather than the navigation software. Use the WorldNav “Language” menu to change the language used for navigation.

     Register your product at teletype.com/register, or mail the included registration form to TeleType.TeleType will then contact you when a software update is released. Updates are released several times a year and upgrading is optional. If at any time you would like to check if there are new versions of the software, contact TeleType. Update information can also be found on the TeleType website under "Upgrades"

     Insert the new (updated) memory card provided to you by TeleType. Access the Navigation function and when the I Agree screen appears, rather than proceed with I Agree, instead press the SD Card Icon found in the bottom left corner. Follow the on-screen instructions to transfer history from a previous card to the new card.
Note: History and Waypoint transfer is available for newer versions of the software such as ver N6.11068L and higher.

      Press Menu, then Find, then Address, and enter an address. Select the resulting address from the results menu; this position will now be visible on the map. Once there, follow the instructions for marking a My Point. Details are found in the WorldNav software guide.

      If you cannot find the category for your POI then it is likely included in the Other category; check this option off and they will appear on the map.

      To adjust the date and time use the WorldNav navigation software rather than the hardware setting. The GPS automatically reads the date and time from the satellite signal; if it is incorrect then the GPS is having trouble finding a signal. Make sure that you are outside with a clear view of the sky, away from larger buildings. Note: You can adjust the time manually within the navigation software by pressing Menu, then GPS Status, then pressing the Change button next to the Date/Time.

     Contact TeleType with the serial number given and you will be assisted.

      The device has lost connection to the software. You can easily reset this information by following the instructions below.INSTRUCTIONS TO FIX THE NAVIGATION PATH

1. While in Map Mode, press the Menu button.
2. Press Route Menu.
3. Press the button with the arrow pointing towards the right.
4. Press Settings on your screen. At the bottom of the screen you will see a graphic of a truck. By pressing this truck you will then be able to change to height, length or weight of your truck by moving the arrows right or left. You can also choose from 9 different classes of HazMat by pressing the HazMat Button.
5. Once you have entered in the correct settings for your truck you can press OK and the changes will be saved.

     On the screen that asks you to press the I Agree button, there will be a software version number on the lower-right corner of the screen. Contact TeleType with this number to find out if your software is the latest.

     Position the target [+] over the road designated in bright pink. Press Menu then Info and the reason for the restriction will be displayed. Also, pressing directly on the [+] will show the reason for the restriction.

     Normally you will want to create a route from the fixed GPS position. You can move the GPS to a location where it will lose the signal so that you can then enter another address or point of your choice using the Find Wizard. If it is impractical to move the GPS to another position, you can temporarily stop the GPS from receiving signals by using the GPS Status screen, where you can turn the GPS status to “Off”. See the software user guide for details.

     Touch the screen anywhere, and you will be in Map Mode (a tool icon appears at the bottom left of the screen). Use your finger to drag the screen in any direction. When you are finished viewing the map, touch the red arrow on the bottom left of the screen to return to Navigation Mode. Remember, when you see the square target [+] on the map, that means you are in Map Mode (which allows you to view the map but does not update your position on the map). When you see the Red Arrow in the middle of the screen, then you're in Navigation Mode so you will see your position move as you drive.

     First, make sure you are in Navigation mode; if you are not in Navigation Mode, your true position will not be shown. The red cursor will be in the middle of the screen while in 2D mode and the cursor will appear towards the bottom of the screen when you are in 3D mode.

     Tap the upper right portion of the navigation panel (the green area showing distance to next turn) to hear a repeat of the upcoming turn instruction.

     Check the Route Settings configuration. In rare cases, if you are using “Shortest” the GPS may take you off the road you are traveling on, then put you back on the same road, if it determines that it would be a significantly shorter distance to use the ramp. It is recommended that you select “Quickest” or “Prefer Freeways” in this case.

     In rare cases where the avoidance of tolls would be impossible or result in an extremely long route, the route will be created ignoring the avoid tolls request. A warning message will appear.

     Detailed instructions for use of the WorldNav software can be found in the WorldNav software user guide. The guide contains screen shots showing details of many of these questions.
