Using GPS
Tools & Extras: Set Sprint Navigation options and access other tools. For example, 
you can view a compass and assign your current location a name, such as Home.
Setting Up an External GPS Device
If you have a global positioning system (GPS) receiver, your Treo Pro smartphone can show 
your exact location on a map. (See palm.com for compatible GPS receivers.) The External 
GPS
 settings do not affect the built-in GPS features of your device. Refer to the documentation 
that came with your GPS receiver for detailed setup instructions, which may include installing 
software on your smartphone. The following steps describe how to set up your smartphone to 
work with an external GPS device. 
1.
Press Start  
and 
select 
Settings.
2.
Select the System tab, and then select External GPS 
.
3.
On the Programs tab, select the GPS program port list, and then select the port for 
applications to use to access GPS information. (This port must also be selected in your 
GPS application’s configuration settings.)
4.
Select the Hardware tab.
5.
Select the GPS hardware port list, and then select the port to which your GPS receiver is 
connected. (This must be a different port from the one you set in step 3 as your program 
port. To connect to the GPS device using Bluetooth
®
 wireless technology, you must first 
set up a partnership between the two devices. See “Setting Up a Bluetooth Connection” 
on page 214.

Tip
Sprint Navigation
 requires signals from GPS satellites. For optimum 
performance, use 
Sprint Navigation
 outdoors or close to a window. The 
satellite signal is diminished when your Treo Pro smartphone is indoors. 
Also, hold the bottom portion of your device to avoid blocking the internal 
antenna, which is located in the upper third of the device.
