Alpha-Numeric Keypad

Letters of the alphabet, symbols, punctuation, and numbers, when available to you, will be displayed on the navigation screen as an alpha or numeric keypad. The alpha keypad will be displayed when the system needs you to input a city or street name. You can also touch Char at the bottom of the alpha keypad to access the numeric keypad when inputting a house address, punctuation mark, or other character. Touch A - Z to return to the alpha keypad.

All characters are touch-sensitive screen buttons. Touch a character to select it.

Select the space symbol to enter a space between characters or the words of a name.

(Backspace): Select the backspace symbol if you have selected an incorrect character.

To make your name selections easier, the system will only allow you to select a character which can follow the last one entered. For example, if you enter Z, you would not be allowed to follow it with T. The system will highlight the available characters and darken the unavailable characters.

If you are unsuccessful when inputting a name, it may need to be selected differently. It is also possible that the map DVD database may not contain that information or the correct search area has not been selected. See Database Coverage Explanations for more information.

Touch-Sensitive Buttons

Touch-sensitive buttons, or screen buttons, are located on the screen. When you have successfully selected a screen button, a beep will sound. These buttons will be highlighted when a feature is available and dim when they are unavailable. There are also some toggle screen buttons that will be light blue when active and dark blue when inactive.
