I have already posted this two years ago, but somehow it was not noticed or ignored.
I'm missing the tracking of the overall distance (yearly ridden distance) or ODO as it is called mostly, this is something all cycling computers have, but somehow it is missing in GB-580.
Currently only the total active distance is recorded (overall distance when measuring) and is hidden in the activity menu (not visible elsewhere).

It also should be possible to put both the active overall distance and complete riding distance (ODO) on one of the custom display pages for easy access.
Plus this data should be visible in the PC application when synchronized.

Hello Icehands,

Can you please tell us where you are located?

So we can see what options we have available.

I do believe we have batteries you can buy.

Hello trim50

As long as your Windows 8.1 laptops are not Windows RT 8.1 they should work.

Please download our latest GPSInfo here :

Then run GPSInfo select the right com port and click start gps.

Also keep in mind you are not running other programs that communicate with the GPS device as the GPS device can only talk to one program at a time.

Please let me know if this solves your issue or you any other questions.

Hello Bob

When a BU-353 is connected to a Linux operating system
It converts the GPS device from NMEA to SiRF Binary because of GPSD

GPSInfo only reads NMEA

Here is the link and instructions on how to get your USGlobalSat GPS Receiver back to NMEA Protocol
1. Download and install this software:
2. Run the Sirf Demo software.
3. Connect your device, choose the correct COM port, and select the 4800 baud rate.
4. Go to Action > Open Data Source.
5. Next, go to Action > Synchronize Protocol & baud rate.
6. Then, go to Action > Switch to NMEA Protocol.
7. In the pop-up window, select the 4800 baud rate under the Baud Rate and click Send.
8. Close the Sirf Demo software.

Now, try your GPS Receiver with the GPSInfo Utility ( to see if the problem persists.

Note: Be sure and not to click on anything else in this software, as you can render your device unusable.

The EB5662RE  V-ANT_DET is controlled by pin16(RF_IN) & pin20 (V-ANT_DET)

Please refer the table for the status of open, shorted or OK.

Pin16(RF_IN)= High & Pin20(V-ANT_DET) = High
Pin16(RF_IN)= High & Pin20(V-ANT_DET) = Low
Pin16(RF_IN)= Low & Pin20(V-ANT_DET) = Low
Pin16(RF_IN)= Low & Pin20(V-ANT_DET) = High


I/O Low Level Input Voltage is -0.4~+0.45V

I/O High Level Input Voltage is +1.26~+3.6V

You could find the I/O Level on page 5 of data sheet.

I have Windows 7 home prem.
I have GPSinfo.
I have a BU-353
I use it on Opncpn.
This was working fine on my windows 7 machine.
I installed it on my Ubuntu 14.04 mach using GPSD and GPSD-clients.
It worked fine.
I came back to my windows 7 machine and it does not work.
When I start GPSinfo and start the GPS the courser moves down the screen one line at a time like it
is trying to work but no data.  Just blank.
I installed the driver recommended to OmarKN (
My BU-353 still does not work.  When I plug it in sometimes (diff usb ports) the message says
"installing driver" I get a blue screen something about a zero.  It goes by very fast. 
The computer restarts and if I remove the BU-353 everything is fine except no GPS.
Sometimes I plug in the BU-353 (diff port) and it tries to work.  No blue screen. 
Then I start GPSinfo and start the GPS.  The courser drops down the screen one line
at a time like the GPS is trying to work but the lines are blank.  No info. 
The red led is blinking.
The BU-353 worked ok before but started to not work before I changed the driver.
I changed the driver in control panel manually.
It still works on the Ubuntu machine. 
I tried all three USB inputs on the windows machine and it does not work.
It seems like there is something keeping the info from being read by the computer.

I have a GlobalSat ND-105C Micro USB GPS that I have tried to run on both my HP laptops which have Windows 8.1 running. The software seems to function for about 30 seconds reading GPS data, and then stopped with a message that says GPSinfo.exe has stopped working. The Windows compatibility software detection says that the GPSInfo is NOT compatible with windows 8.1.

I have done everything I know how to do to get this issue resolved short of through the system overboard.

Please help>..

I wonder where I can buy a new battery to replace the old. The reference sample inside the battery is EXA AL553436B.
Thank you.
