### Touch-Sensitive Screen Buttons

These buttons are located on the screen. When selected, a beep sounds. Screen buttons are highlighted when a feature is available.

### Alpha-Numeric Keyboard

Letters of the alphabet, symbols, punctuation, and numbers, when available, display on the navigation screen as an alpha or numeric keyboard. The alpha keyboard displays when the system requires entry of a city or street name.

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

A-Y (Accent Alphabet): Select to get letters with accent symbols. This button may toggle to A-Z.
A-Z (Alphabet): Select to get letters from the alphabet. This button may toggle to A-Y.
0-9 (Numbers): Select to get numbers and punctuation marks.
(Space): Select to enter a space between characters or the words of a name.
Backspace: Select if an incorrect character has been entered.

To make name selections easier, the system only highlights the characters that can follow the last one entered. For example, if a Z is entered, a T may not be available for selection.

If a name does not display after entry, it may need to be entered differently or the map DVD disc may not contain that information. See Database Coverage Explanations for more information.
