Telenav for Sprint Supported Devices: v7.1 for Android devices - Manual (Page 90)

Why does GPS not work near buildings and other tall objects?
Your device requires signals from GPS satellites in order to work, so it needs a clear view of the sky. Dense materials
(such as concrete, rock, steel, heavy wood), tall buildings, terrain features (like mountains, ridges, and cliffs), and large
trees can block or degrade GPS signals and may make it impossible to determine your location.
GPS satellites are not always immediately overhead and could be anywhere in the skies at any time, even low on the
horizon; however, there are enough satellites in orbit so that four or more will be view of your device if not blocked by
large objects, terrain, or dense materials.
How do I know that my device is receiving GPS signals?
Telenav GPS Navigator alerts you if your device is not receiving GPS signals. If this happens, move to an area where
there is a clear view of the sky so your device can receive GPS signals from space.
How can I get a route when there is no GPS?
When there is no GPS, the navigator is not able to provide turn-by-turn navigation in real time. However, you can get a
static route with a summary of turn-by-turn directions, detailed traffic information, and a map view of your entire route. To
do this, select Drive To and enter a destination. On the Trip Confirmation screen, choose the Directions button to get a
static route. Alternatively, you can do the following:
1. Choose the Route Settings box at the top of the screen for editing options.
2. In the screen that appears, tap the Origin choice and enter or select an address.
3. When you choose Get Route >> Directions, the Navigator will show a screen with turn-by-turn
directions.
4. You can choose Route on the navigation screen to view a map summary or traffic conditions along
your route.
