1. GETTING STARTED
GlobalSat Bluetooth GPS receivers utilize a Bluetooth (short distance wireless protocol) and a built-in
active antenna for high signal tracking sensitivity. Based on the SiRF Star III Low Power chipset, our
GPS receivers support all functions (single sat updates in reduced visibility, superior urban canyon
performance, foliage lock for weak signal tracking, etc.). Our Bluetooth GPS receivers are well suited
for use with PDA’s, Smartphones, tablet PC’s and notebook PC’s and laptops which are already
Bluetooth enable. GPS receivers can be used in a wide variety of applications from in vehicle
navigation to and outdoor recreation and commercial applications.
2. THE BT-359
The BT-359W shown above and the BT359C (not shown) are models which can be found in North America, while
the BT-359S can also be found in Europe. There are no differences between these models with exception to the
cosmetic faceplate used. The “W” is a radio wave patter, the “C” is a glossy black faceplate, while the “S” has the
appearance of a solar cell graphic. Electronically they are the same device.

Power Jack
The mini-USB is a power jack that lets allows you to connect to either a DC vehicle charger or an AC
charger home/office charger for re-charging the internal Lithium-ion (Li-ion) battery. The voltage input
into the BT-359 must be 5VDC (01.6 A) center positive connector. You can also use the USB
interface cable to charge directly from your PC’s USB port. (The USB interface can only be used for
charging the GPS receiver’s battery and cannot be used to transfer data.) Upon powering your new
BT-359 GPS receiver for the first time it may require as much as 6 hours to fully charge, thereafter
charging times may be reduced. The built-in regulator will prevent your battery from being
overcharged, however it is always best to unplug the GPS receiver from the charger after charging has
completed and not to leave it connected for extended periods of time..
Status LED Functions
Mini-USB Power Port
(not for data transfer)
Power Status LED (Red/Yellow):
Red ---- Battery power is critically low. (charge immediately)
Yellow ---- Battery is currently charging .
LED off ---- Battery is charged (partial or full).
GPS Status LED (Green):
Blinking ---- GPS position is fixed (GPS signal is being received)
Steady light ---- GPS position is not fixed (no GPS signal)
Bluetooth Status LED (Blue):
Blinking (Slowly) ---- Not connected to a Bluetooth device.
Blinking (Quickly) ---- Connected to a Bluetooth device.
Auto Shut-Off (Power-Saving Mode)
To conserve battery life, whenever the GPS receiver does not detect a Bluetooth signal for over 10 minutes, the BT-
359 will automatically shut off, but only when operating from it’s internal Li-ion battery.
If connected to an external power source (AC or DC charger), then the BT-359 will remain on.
We strongly suggest that you first test your USG GPS with the included GPS Info utility program to confirm that the
GPS receiver if functioning properly on your PC and that you have successfully configured the right COM Port
setting. Once this has been done, close the GPS Info program and start your application for COM port
configuration.
NOTE: By default, your PC will not allow you to run multiple applications from a single COM port. It is important that
you close any previously opened GPS application before switching to another GPS application as the GPS receiver
and data will not be found by the new program.
There are special utilities available to split data into multiple COM ports for use by more than one application

5. INITIALIZING YOUR GPS RECEIVER
Before using your Bluetooth GPS receiver for navigation (especially for the first time), the receiver must
obtain a local GPS fix (coordinates) of the current position. To do this, take your device loaded and
configured with your mapping software to an open area that has a clear view to the sky. Start your
software (or the included GPS Info utility program) and wait for initialization of the GPS to complete.
This may take a few minutes depending on various factors such as the distance of the current
coordinates from the last time the GPS receiver was activated, GPS signal strength and surrounding
terrain (tall trees and buildings can block the satellite signals). Once the RAW GPS data is displayed
onto the screen, if applicable for your software, a fix has been initialized (Green LED on the GPS will
also start to flash). In some cases initialization can take up to several minutes depending on the
conditions mentioned above before complete GPS data will be displayed on the screen.
Coordinates scrolling with zero’s means that the port connection is complete, but the satellite data is not
being received yet (possibly still initializing or in a bad area for satellite reception).
6. USING / TESTING YOUR GPS RECEIVER (WIN / PPC only)
Once your Bluetooth GPS receiver has been paired with your device and your personal mapping
software have been installed and the COM port configured properly, you can begin to use your
navigation system. If you don’t have a mapping, or navigation software to try out your new GPS
receiver, we’ve included a GPS test utilities called “GPS Info” (GPSInfo.exe) for Windows and Pocket
PC devices located in the Win directory and “GPS Utility” (Mac_GPS_Utiltiy_V2.dmg) is located in the
.Mac directory of the CD-ROM.
Always select an area in the vehicle where the GPS unit will be secure and not obstruct normal driving,
visibility and safety, but still maintaining a “view to the sky” in order to receive satellite data.
WIN and PPC devices:
It is recommended that you first load and test your GPS receiver with the GPSinfo.exe. This process
will confirm you have found correct COM port number and have configured it properly.
1. Run GPSinfo.exe to load the utility.
2. Enter the proper COM port for your GPS device (see COM Port Verification above)
3. Set COM port to Baud rate: 34800
4. If no errors have been made in configuration, there should be GPS data being displayed in the
window, which is confirmation that the communication between the GPS device and the “GPSinfo”
software is working properly.
5. If there is no GPS data displayed (or data with multiple zeros in them), please exit the software and
unplug the GPS receiver from the USB port and reinsert it after 10 seconds to reset the device.

7. FAQ’s
What is the difference between the BT-359W and the BT-359S?
There is no difference between these two models with exception to the cosmetic faceplate used. The “W” is a radio
wave patter, while the “S” has the appearance of a solar cell. Internally they are the same device.
I am not getting GPS data into my application on my Windows PC.
1. Check your DEVICE MANAGER to confirm the COM Port number assigned to the GPS. Then be sure
this is the same COM port number configured in your application.
2. Be sure your Baud rate is configured correctly at:
Baud Rate: 38400
Data bit: 8
Parity: None
Stop Bit: 1
Flow Control: None
3. Configure the GPS Info utility with the correct COM Port and test your GPS receiver first before using it
in your application.
Will the GPS work with other Street Mapping software?
GlobalSat GPS receivers provides standard NMEA data for mapping software to use and convert to coordinates
and should work well with most any NMEA compliant software on the market today.
How accurate is the GPS?
The Gloablsat GPS is WAAS/EGNOS capable, and for units sold in North America through authorized resellers,
these units are WAAS/EGNOS enabled unless otherwise stated. Accuracy can be between 1~5 meters 2D RMS
with WAAS enabled and 10-15 meters 2D RMS WAAS disabled
What is ideal GPS environment?
The GPS requires an open, clear view of the sky. Buildings, covered parking areas, tunnels and dense foliage can
cause the GPS receiver to be unable to get a location fix.
If you are parked in a covered parking lot or near a tall building, it is recommended that you drive away until you
have a clear view of the sky before using the GPS receiver. You may need to give the GPS a few minutes to find or
get a fix its location.
How do I know if the GPS is ON?
If your PC is on and the COM port was configured properly, the GPS receiver is on and receiving the streaming
GPS data. This can be verified by opening your mapping software program. In addition, the GlobalSat GPS has a
built-in LED status indicator that shows the following:
LED OFF: GPS receiver is off (no power).
LED ON (solid): No fix, searching for GPS signals.
LED FLASHING: Position fix established and GPS signals are being received.
Why does the GPS not work near buildings and other tall objects?
The GPS uses satellites in the space to find out where it is. Therefore it needs a clear view of the sky. Tall buildings
and other objects that block the receiver’s view to the sky make it infeasible to determine your location. Sometimes
the satellites are not overhead but near the horizon. In these cases the GPS must have a clear view of the horizon.
Other Comments-
Please allow an adequate amount of time for the GPS receiver’s boot-up (TTF) to complete before contacting
Technical Support.
