Lock-on-Road: This function of iGO will always keep the blue (yellow at night) arrow
representing your actual position on the nearest road. This automatic feature is
necessary as the position given by the GPS receiver is not perfectly accurate. Under
normal circumstances Lock-on-Road will eliminate the occasional position error. If
the corridor of error is too large, your position may be shown over a different street
on the map. You can only avoid that by using good quality GPS equipment
positioned so that it has a direct view to as large a portion of the sky as possible.
Lock-on-Road is always active in iGO. See also Page .23
Lock-to-Position: When GPS position is available, iGO will automatically keep
moving the map to always have the blue (yellow at night) arrow, representing your
actual position, on the screen. You can move the map to lose this position. Then the
Lock button appears on the screen. Tapping it will re-enable Lock-to-Position. See
also Page .30
Map Orientation:iGO is able to rotate the map for your convenience. If you choose
Track-up mode, the map will be rotated to look in the direction of your heading.
Selecting North-up, the map remains oriented to have North toward the top. Use the
left and right hardware buttons to turn your map in the direction you wish. This will
immediately turn off the automatic rotation. A small compass in the top right section
of the map screens (
Page ) will always show the current direction of the map. Map
orientation should not be mixed up with Screen orientation.

NMEA (National Marine Electronics Association): This is the name of a
communication protocol format. This association issues standards for interfacing
marine electronic devices. One of their standards is NMEA-0183 that defines
electrical signal requirements and a data transmission protocol for time and position
data. This is today’s standard for not only marine but also all other GPS devices. iGO,
as well as most GPS devices, will default to using this protocol out of the box.
North-up: A kind of map orientation having the map rotated to have North toward
the top of the screen. See also Track-up and Map Orientation.
POI: Points Of Interest, exact map locations of important points saved in a database
together with their name, category and subcategories (e.g. Service/Fuel/Autogas),
address, phone and fax number, and other important information. Use the versatile
search system in iGO to find the appropriate POI near you, your destination or any
other given location on the map (Page ). You can also have your favourite places
saved as ‘My POI’ in
81
iGO.
Screen Orientation: Depending on how you prefer to hold the PDA in your hand or
how you have it installed in your car, you may want iGO to display all its screens in a
portrait, landscape, or left-handed landscape mode (Page ). This setting is
independent from the corresponding setting in the operating system. Screen rotation
in iGO can even be used with PDAs originally not capable of displaying landscape
orientation. Screen orientation should not be mixed up with Map orientation that does
not affect the appearance of iGO, only the map itself.
