Chart Rotation; Autozoom; Screen Amplifier; Overzoom - Geonav 6 Sunshine User And Installation Manual

Functional Characteristics

Cursor mode (Manual)
When in Cursor mode, the manual cursor is displayed. It is
possible to edit a route, insert or delete markers, display navaid
information etc., but it is not possible to gain access to the
depth sounder window. By pressing one of the four arrows in
the CURSOR key, the unit switches from Navigation to Cursor
mode, and the screen is centered in relation to the manual
cursor. To return to Navigation mode press PAGE.

Chart rotation

Charts are traditionally displayed in
north-up mode. This, however, does not
correspond to reality. For example,
when traveling southwards, the chart
shows, on the right side of the boat,
what is actually located on the left side,
and vice versa.
The Chart Rotation function allows ro-
tating the electronic chart displayed ac-
cording to the plotted route (COG -
Course Over Ground) as detected by the
GPS receiver. Since the COG value var-
ies continuously, a filter has been in-
serted to prevent the chart from bounc-
ing.
To activate the Chart Rotation function,
press PAGE to display the menu, select
SETUP, then CHART ROTATION and
ON. A message will prompt the user to
select the requested maximum range be-
fore activating the chart rotation.
The northern direction will be indi-
cated by the symbol .

cally the boat's position and the target waypoint at the best
available chart range. As the boat
approaches the target waypoint,
the unit will automatically zoom
in. Once the waypoint is passed,
the unit will select the best range
to display the boat's position and
the following waypoint.
To activate the Autozoom function, press ZOOM+ until the
"AUTOZOOM ? ENTER = YES" message is displayed.
To deactivate the Autozoom function, press the ZOOM key once.
When the GEONAV is turned on, and if at least one waypoint
has been previously entered, the Autozoom function is auto-
matically activated.

Screen Amplifier

This function automatically redraws the chart according to
the boat's course, to maintain 2/3rds of the screen ahead of
the boat, provided that the boat's
speed is greater than 3 knots.
This function will be activated
only if no waypoint has been
previously inserted.

Overzoom

The Overzoom function allows
the chart scale to expand any-
where up to 1/4 NM. The
Overzoom does not provide any
additional chart detail, but im-
proves only the readability of the
existing information, thus act-
ing as a magnifying glass.
When the Overzoom is activated,
the unit will warn the user by
