Just wondering, before you use the SiRFDemo, was the device outputting data with the GPSInfo?
If so, did you make any changes/updates with the computer before using the SiRFDemo?
Also, how were you able to setup the BU-353 with the SiRFDemo? Can you please provide a step by step procedures?
Did you click on any selections/options in the program?
By the way, what is the operating system and version of your computer?
Perhaps, you can reset the unit back to its default settings by unplugging this device/leaving it alone for about 72 hours.
