Why do I need a PIN number?
You may need a four-digit PIN to log in to AT&T Navigator for the very first time. It is unique to your account and
identifies that your account is active.
How do I find my PIN number?
Your PIN can be found in the About menu. See Page

for details. You can use this PIN for pre-planning on

.
I have recently changed phone numbers. How do I move my subscription over to my new phone number?
Contact your carrier to change the phone number.
Does AT&T Navigator use up my voice plan minutes?
AT&T Navigator uses data to provide its navigation functions. Using data does not use any of your voice minutes.
However, the Speak It feature within the AT&T Navigator application that allows you to make calls to businesses
does use voice minutes.
How do I increase or decrease the voice prompt volume and control the backlighting?
Speaker volume can be controlled with the volume buttons on the side of the device. The backlight can be
controlled from within AT&T Navigator’s
Menu
>> Settings >> Navigation >> Backlight menu.
How do I conserve battery life on my device?
Set the backlight to “On at Turns”
in
Menu
>> Settings >> Navigation >> Backlight menu. This option turns the
backlight on only when a turn is approaching.
How accurate is the GPS?
GPS accuracy can range from 20m (approx. 65 ft) to 100m (approx. 328 ft). Most of the time, the GPS is accurate
to less than 50 meters (approx. 164 ft).
What are ideal conditions for GPS navigation?
Ideally, a device with a GPS receiver needs a clear view of the sky, starting from about five to ten degrees above
the horizon. Solid or massive obstructions can reduce accuracy or block GPS signals, and may cause extended
initialization time (time to first GPS fix). Common obstructions include tall buildings, covered parking lots, tunnels,
trees, and terrain features.
If you are parked in a covered parking lot or near a tall building, it is recommended that you move to an open area
and then begin to use AT&T Navigator.
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.
