ing navigation (Cockpit screen) but
there is no Add POI button in the Cursor
menu.
For driving safety reasons the Add POI
function is only available on the Map
screen. If you are the driver, save it as a
POI later, when you reach your destination.
If you are not driving, switch to Map mode,
where the Add POI button is available.
Q. I would like to create a new POI but
there are others near its location, and
the new menu point (POI) opens the list
of POI instead of creating a new one.
Look for the New button in the bottom left
corner of the newly opened list. Using that
button you can add your new POI as if it
was opened from the Cursor menu.
GLOSSARY
2D/3D GPS Reception: The GPS receiver
uses satellite signals to calculate its (your)
position. Depending on the current posi-
tions of the ever moving satellites in the
sky, and the objects in your environment,
the signal that your GPS device receives
may be weaker or stronger. Your GPS
needs strong signal from at least four sat-
ellites to give a three dimensional position
including elevation. If fewer satellites are
available, it may still be possible to calcu-
late the position but the accuracy will be
lower and the GPS device will not calcu-
late elevation. This is called 2D reception.
Cydle shows the quality of reception on the
Main menu, the GPS Data screen and both
map screens. Note that 2D and 3D GPS
receptions have nothing to do with the 2D
and 3D display modes of the map. That is a
way of representing the map on the screen
independently from the GPS reception.
Accuracy: The difference between your
real position and the one given by the
GPS device is affected by several different
factors. The GPS is capable of providing
a guess of its current error based on the
number of satellites it can receive a signal
from, and their position in the sky. This in-
formation is shown in Cydle on the GPS
Data screen. Use it as a general reference
only. Note that several other factors affect
the real accuracy, some of which the GPS
is incapable of estimating (e.g. signal delay
in the ionosphere, refl ecting objects near
the GPS device, etc.).
Active Route: A route is an itinerary
planned to reach your chosen destina-
tions. A route is active when it is used for
navigation. Cydle has only one route at a
time, and it is always active until you delete
it, reach the fi nal destination or exit Cydle.
When there is more than one destination
to reach, the route is cut into different legs
(from one via point to another). Only one
of these legs can be active at one particu-
lar time. The rest of them are unused and
shown in a different color on the map.
Automatic Route Planning (Autorouting):
You only need to set up your destination,
and based on its map, the software will
automatically fi gure out which roads you
need to take, and the turns you need to
make to get there. Cydle will let you select
multiple destinations, and customise some
important routing parameters.
Automatic Route Recalculation: If this
function is enabled, Cydle recalculates your
route if you deviate from it. When you miss
a turn or avoid a roadblock, Cydle waits for
a few seconds to be sure you do not follow
the route any more (you can fi ne-tune it in
Advanced settings), then recalculates the
route based upon your new position and
heading.
Automatic Day/Night Colors: Based on
the time and position given by the GPS
device, Cydle is able to calculate when the
sun rises and sets at your current location
