8 Glossary

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

if you are unfamiliar with some of them.

¾ 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. Mio Map shows the quality of

reception on the GPS Data screen (4.4.3) and both map screens (4.3.9). 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.

¾ 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

Mio Map on the GPS Data screen (4.4). Lower numbers indicate better

accuracy, where 1.0 is near-perfection. 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.).

¾ Active route: A route is an itinerary planned to reach your chosen

destinations. A route is active when it is used for navigation. Mio Map has only

one route at a time, and it is always active until you delete it, reach the final

destination or exit Mio Map. 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 (4.2.11.3). The rest of them are

unused, and inactive.

¾ 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.

Mio Map will let you select multiple destinations, and customise some

important routing parameters (6.3).
