and supports all functions (Single Sat updates in reduced visibility, Superior urban
canyon performance, FoliageLock for weak signal tracking, etc.). The BT-359 is well
suited to system integrations including PDA, Smart phone, Tablet PC and Notebook
PC with Bluetooth devices. It satisfies a wide variety of applications that are
purposes in automotive and outdoor recreation navigation systems.

2.4 Power-saving Function

automatically, and all the LED will go off simultaneously.

2.5 Auto Shut-Off Function
By default, your BT-359 has a built-in timer that will automatically power down your
BT-359 GPS receiver whenever it looses the Bluetooth paring connection to the host
device for more than 10 minutes. This will help to keep you from returning to a dead
GPS battery in the event you accidentally might have left the vehicle and forgot to
turn off the GPS.
Auto Shut-Off Override Switch
This feature is not found on all models of the BT-359 and is usually not required by
most users. However, for those who may have applications that require an override
to the Auto Shut-Off feature to keep the BT-359 powered at all times regardless of
the Bluetooth paring status, then only these GPS models, the BT-359 can be used
since they come equipped with the special override slide switch located under the
battery.
To disable the Auto Shut-Off feature, simple use a thin sharp object like a pin, or
paper clip to gently slide the switch into the OFF position. The GPS will now remain
ON indefinitely until the power switch is turned off, or until the battery is dead, so use
caution when operating in this mode.
Auto Shut-Off Enabled = ON
Auto Shut-Off Disabled = OFF
We strongly suggest that you first test your 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.

connecting to the BT-359. Some PDAs may need the Bluetooth passkey,
the passkey is “0000”.
3. Check the number of COM port used by Bluetooth.
4. Run the suitable mapping/navigation software and select the correct
COM port & baud rate: 38400
4.2. For PDA with Bluetooth Compact Flash card
1. Turn on the power switch in BT-359.
2. Please refer to the user manual of Bluetooth Compact Flash card to
enable it to connect with the BT-359. Some Bluetooth devices may need
the Bluetooth passkey, the passkey is “0000”.
3. Check the number of COM port used by Bluetooth.(Example COM 6).

5. How to test your Bluetooth GPS Receiver?
The testing program only supports the Microsoft Windows CE & Pocket PC based
PDA platform.
1. Run the “GPSinfo.exe” to execute the installation procedure of testing
program (via PC and ActiveSync).
2. Run the “GPS Information” program from “Start →Program files” of PDA.
Here is the description of “GPS Information” testing program:
User must select COM port, Baud Rate (38400) and click the [Star GPS] button
to start receiving GPS data.
Note: The Bluetooth device in most of the applications have an
“auto-detect” feature that you do not need to select the Baud Rate.

6. Troubleshooting
Bluetooth is unable to connect
A) Check if the GPS Bluetooth indicator is flashing normally. That is, flash one per
each three second means the product is under standby mode; flash once per
second means Bluetooth has been online already.
B) Check if energy level is sufficient. If red LED is lid up, then the battery level is
insufficient, please recharge it until the red indicator is off (recharge is complete).
GPS cannot be positioned
A) Check if GPS indicator operates normally or not. If the indicator is constantly lid
up, it means that GPS is in operation; if the indicator is flashing, it means GPS is
positioned already.
B) If GPS cannot be positioned for long, apply GPS info software to make a Cold
Start first, and then move to an open space performing the positioning task.
Check if power level is sufficient. If the red LED lights up, it means the power is
insufficient, please recharge it until the red indicator is off (recharge is complete).
7. FAQ
zI 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.
zWill the GPS work with other Street Mapping software?
Globalsat GPS receivers provide 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.
zHow accurate is the GPS?
The USB 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 up to 5 meters 2D RMS
with WAAS enabled and 10-15 meters 2D RMS WAAS disabled
