Pioneer AVIC-S2 RU - Manual (Page 28)

This function modifies the vertical viewing angle of the map in 3D mode. You can
change the angle in a wide range starting from a top down view (2D view is
seamlessly integrated) all the way to a flat view that lets you see far ahead.
The automatic Smart Zoom function will do the necessary tilting for you when
navigating (gives a flat view if the next turn is at a distance to let you see far ahead
and raises the angle when approaching a turn to give you a better view of the
upcoming turn). If you manually change the view angle, Smart Zoom will no longer
tilt the map by itself (automatic zooming and rotating remains active).
You need to tap the Back button (Page 28) to return the tilt control to Smart Zoom.
Note: 3D view is only useful for navigation. As you zoom out, the view angle will
automatically be raised. When finally 2D view is reached, these buttons disappear.
When you zoom back in, 3D view will gradually return.
4.3.4 Back to navigation - lock to GPS position and heading (No. 6)
This semi-transparent icon is displayed if GPS position is available, and the map 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 AVIC-S2 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 Back 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.
