With ignition key at MAR, if au-
thentication fails, system starts work-
ing as usual, but the user is asked to
enter the 4-digit "Master Code" to al-
low access to the standard functions.
Master code is unique for each
CONNECT Nav+, and is stored in its
memory and can not be reset.

A specific panel allows code inser-
tion, fig. 7. Behaviour of this box is
similar to PIN insertion request, but
the dialog box itself is generated on a
wholly blackened screen.
Numeric keys and "ON" button are
enabled only, 19-fig. 1.
After the code is entered, a second
panel notices the user that the au-
thentication procedure is in progress,
fig. 8.

In case the correct code is provided,
the system is fully enabled. On the
contrary, if a wrong code is entered,
screen is cleared and previous box is
shown again with the following string:
"Incorrect code entered. Enter mas-
ter code or turn off system with ON
pushbutton" 19-fig. 1.
There is no upper limit to the num-
ber of wrong codes that can be en-
tered.
