Tip: These objects are normally displayed using textured polygons that look natural to the eye.
You may wish to switch the textured display off to free some of the resources of your PNA by
replacing textures with plain coloured surfaces.
Current position and Lock-on-Road
When your GPS position is available, an arrow shows your location on the map.
The direction of the arrow represents your heading. The arrow is sized and vertically rotated
with the zoom and tilt levels to always look realistic.
ASUS GO has a built-in Lock-on-Road feature that always puts the position arrow on the
road, on the axis of the street in case of one-way streets, or on the side of the road where you
drive (e.g. on the right in Germany and on the left in the U.K.) on two-way roads.
