device, you may need to manually specify the GPS port in your GPS program's configuration settings.
For manual settings, refer to the documentation that came with your additional GPS software program.
Identify the COM port for my GPS receiver
The GPS receiver on your GPS enabled HP iPAQ is set to default configurations. To verify, tap
Start > Settings > System> External GPS.
Improve a slow GPS connection
To improve GPS connection performance on HP iPAQ GPS enabled device, you need to download the
latest GPS Connection Utility data file.
Even though GPS on your HP iPAQ is able to connect to the GPS satellites without enabling the GPS
Connection Utility, it may take a few minutes longer and even up to five minutes to locate the satellites
if you do not use this utility.
Since the GPS satellite data update files are small, you should be able to download them with a little or
no impact to device performance. However, you need to buy a wireless data plan (GPRS, EDGE, UMTS,
HSPA, or Wi-Fi) from your service provider before you can use this feature and GPRS connection
charges may apply. Check with your service provider to see if additional charges apply.
Troubleshoot frequent GPS signal loss
To improve the satellite signal to the GPS enabled HP iPAQ, go outdoors and start the GPS navigation
software. Place the HP iPAQ where there is a clear view of the sky or on the dashboard of a vehicle
that does not have thermal glass windshields or windows. A direct line of sight is required between the
HP iPAQ and the GPS satellites to access information from the satellites.
NOTE: Interference might take place close to tall buildings, large trees, and under very cloudy or
overcast skies, all of which can block the satellite signal from reaching the HP iPAQ. Try to avoid these
obstructions before using GPS.

Interference Type How to Avoid
Vehicles with thermal glass windows and windshields. Place the HP iPAQ where there is a clear view of the sky or on
the dashboard of a vehicle that does not have thermal glass
windows.
Equipment radiating Radio Frequency (RF) energy or emitting
strong electromagnetic radiation. For example, microwave
ovens, high-power cordless phones, CB radios,
Walkie-talkies, HAM equipment, or X-ray and MRI machines.
Move away from interference source or switch off the
interference source.
Tall buildings, large trees, and very cloudy or overcast skies. Move away from interference source so there is a clear view
of the sky.
