Track-up: A kind of map orientation when the map is rotated to look always in the
direction of your heading. See also North-up and Map Orientation.
Via point: Routes in Uniden Navigation can have several (as many as you want) different
destinations to reach in a specic order. All these points except the nal destination
are called via points, as the route goes ‘via’ (through) them. The destinations can
be seen in the Route Information screen on the Route line (Page 39), and each via
point is announced by the voice instructions as you approach and when you reach it.
Should your via point serve as a stopover, navigation continues automatically as you
depart. Navigation will resume even if you turn off and on your PDA or restart Uniden
Navigation.
Zoom In and Out: The Zoom function is used to change the scale of the map. Use
Zoom In to scale down the map to see less of it but in more detail, and use Zoom Out
to scale the map up to have a broader view of that part of the map with fewer details.
