has been moved. It also appears when you scale or tilt the map while Smart Zoom
is enabled.
This semi-transparent icon is displayed if GPS position is available, and the map has
been moved or rotated. It also appears when you scale or tilt the map while Smart
Zoom is enabled.
Normally Uniden Navigation positions the map to keep the GPS position visible
somewhere on the map (when North-up orientation is selected), or always at the
bottom centre of the map (when Track-up orientation is selected).
If you manually move the map, it will freeze the map in the new position. To return to
the GPS position, use this Lock button.
Rotating the map in any direction will only freeze the orientation of the map, but it
keeps on moving to keep the GPS position visible. Use Lock to return to North-up or
Track-up orientation (the one previously selected).
Scaling or tilting the map also stops the automatic zooming or automatic tilting
respectively. To reactivate Smart Zoom, tap this button.
When Smart Zoom is enabled, scaling or tilting the map also stops the automatic
zooming or automatic tilting respectively. To reactivate Smart Zoom, tap this button.
This button has a hardware button equivalent: please see seperate operation manual.
Tip: In Advanced settings you can set a delay time after which Uniden Navigation
pushes the Lock button for you automatically (Page 68). This can be turned on for
re-enabling both Lock-to-Position and Smart Zoom.
4.5.5 Cursor (No. 7)
As described earlier (Page 23), if you tap the map somewhere or select one specific
item in Find, it will become the selected point on the map, marked with a small red
dot and radiating red circles to make it conspicuous. You can use this point as starting
point, via point or destination for your route, you can search for a POI near it, mark it
with a pin, or save it as a POI.
4.5.6 Map scale (No. 8)
The scale indicator is only available on the Map screen. In 2D map view it represents
the scale of the map. In 3D view it is the scale of the nearest part of the map only.
