The smart speller assists you when entering information into the radio. When entering information (such as a search for a navigation address), the keyboard only enables strings of letters that match the entries in the database.

After a number of letters have been entered, the system will predict the word or location that you are trying to enter by providing matching data from the database. For example, entering "ROCH" could cause the system to suggest "ROCHESTER".

The smart speller can also accept partial entries. If pressing OK with only a partial string of text, the radio will provide a list of items that begin with that text. For example, entering "SAN" and pressing OK could provide a list including "SAN FRANCISCO" and "SANTA ANA".

The smart speller can also assist when entering multiple words. Entering the first few letters of each word, separated by a space, will cause the system to respond with matching words. For example, entering "N D" (including space) could cause the system to respond with "NORTH DAKOTA".
