7 Glossary

The manual may contain many technical terms. Please look below for an explanation

if you are unfamiliar with some of them.

2D/3D GPS reception: The GPS receiver uses satellite signals to calculate its (your)

position. Depending on the current positions 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 satellites to

give a three dimensional position including elevation. If fewer satellites are available,

it may still be possible to calculate the position but the accuracy will be lower and the

GPS device will not calculate elevation. This is called 2D reception. This GPS device

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 information is shown in this GPS device 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, reflecting objects near the GPS device, etc.).

Active route: A route is an itinerary planned to reach your chosen destinations. A

route is active when it is used for navigation. This GPS device has only one route at

a time, and it is always active until you delete it, reach the final destination or exit this

GPS device. 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 particular 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 figure out which roads you

need to take, and the turns you need to make to get there. This GPS device will let

you select multiple destinations, and customise some important routing parameters.

Automatic route recalculation: If this function is enabled, This GPS device

recalculates your route if you deviate from it. When you miss a turn or avoid a

roadblock, This GPS device waits for a few seconds to be sure you do not follow the

route any more (you can fine-tune it in Advanced settings), then recalculates the

route based upon your new position and heading.
