3.2 Software keyboard
Overview If text entries are necessary, a software key appears in the lower
area of the screen.
3.2.1 Enter characters with the software keyboard
You may carry out all entries with your finger on the character
keyboard. But you may enter capital letters only.
You need not enter small letters or special characters when
entering a destination's town or street name. AVIC-S1 replaces
these characters automatically. When you are looking for, e.g., a
French town called "Héroïnès", simply type "HEROINES".
Smart keyboard The system has a database and therefore knows which cities or
streets begin with the character combination you have entered.
As soon as you have entered a character, the system deactivates
all characters that do not exist in combination with the already
entered one(s).
The city or street names that begin with the previously entered
character combination will be listed above the keyboard.
