Alpha-Numeric Keypad

Letters of the alphabet, symbols, punctuation, and numbers display on the navigation screen as an alpha or numeric keypad. The appropriate keypad automatically displays whenever the system requires more information. The alpha keypad displays when the system requires input of a city or street name. The numeric keypad displays when the system needs input of a phone number or house address.

Touch a character on the screen to select it. The 0 - 9 screen button can be touched at any time from the alpha keypad to access the numeric keypad.

(Space): Touch to enter a space between characters or the words of a name.

(Backspace): Touch if an incorrect character has been selected.

To make name selections easier, the system only allows selection of a character that can follow the last one entered. For example, if a Z is entered, a T is not available to select. The system highlights the available characters.

If a name is not available after input, it may need to be entered differently, the map DVD database may not contain that information, or the correct search area has not been selected. See Database Coverage Explanations.

Touch-Sensitive Screen Buttons

Touch-sensitive buttons are located on the screen. After selecting a button on the screen, a beep sounds. This feature can be turned off. See Configure Menu for more information. Screen buttons are highlighted when available. There are some toggle screen buttons illuminate in color when active.
