SirfTech is a Pocket PC, PC and Smartphone program for checking and setting practically all SiRF GPS settings. Please find it at: http://w5.nuinternet.com/s660100031/SirfTech.htm

Would really like to get your feedback. I am reluctant to use Sirf programs like this or SirfDemo, as I do not have the technical understanding to work with all the settings. I am concerned that I might render my gps receiver unuseable or less proficient than the factory settings.

gpspassion,
All the settings you get using the Poll Navigation Parameters command are actually on the Mode Control, Static Navigation, Dop Mask, Elevation Mask, Power Mask, DGPS Source, DGPS Mode, Trickle Power, Low Power and Advanced Power Management property sheet pages. They are needed on those pages for possible settings changing, and I don't want to add confusion by showing them in more places.
jeb,
You are as sensible as one could whish more people would be. These programs are really experts tools. Your best option I think is to find and study the SiRFDemo User Guide. I did avoid implementing the potentially dangerous UART and protocol commands. The power saving commands are also potentially dangerous. Setting too much power saving can make it VERY difficult to communicate with the GPS. So far I only handle this by issuing a general warning and a cancel option when setting any of these. All other changes should be easily changed back to factory settings by issuing a Factory or System Reset from the Initialize Data Source property sheet.
I enjoy mastering technical details but I am not too good at documenting them in a simple and clear way. However I do plan on putting notes on some settings that are most likely to improve something.

I see your point, but I must say I'm a fan of the "poll navigation settings" found in SiRFdemo or SPGPS as they give a good and quick overview of all the system settings, I wasn't suggesting you allow changes to be made from that screen of course.

Dennis,
Looks like a very useful utility, however, I installed SirfTech on my iPAQ 2495 (WM5) with iGuidance 2.1.3 and a BT-338. iGuidance, and other utilities, detect the GPS just fine on COM8 at 4800 baud. SirfTech seems to be unable to locate the GPS at all, and when I do a "Find GPS" it freezes the PDA completely, requiring a soft-reset.
Happy to help debug if I can...

Derek,
Thanks for your debugging offer. I could use some help and will try to mail you a debug version.
Is there something I should know about WM5 "gps manager" or bluetooth manager? Or is that something every WM5 or bluetooth user should know how to handle?

Tested successfully in the Loox N520 tonight.
Quite like the "live" NMEA data screen, pretty unique although it doesn't fit on one page even in landscape mode, could you make it scrollable maybe ?

No Poll Navigation Parameters I'm afraid but 'a good and quick overview of all the system settings' is planned. It should not be the raw sometimes bitmapped values but a bit more understandable text descriptions. And a few more than those that are in Poll Navigation Parameters. I aim to place the screen text also into the clipboard in a format suitable for pasting into an Excel column. That way it would be easy to compare different sets of settings.
The "live" NMEA data screen was a bit more readable than the usual scrolling ones. However it was only an intermediate stage. No use to see the same info in up to three different NMEA messages. Now, in the version available for download, I parse all the messages and display a few of the values.
Next in functionality is graphs of values versus time and track plot. All for evaluating changes to settings.
For the Bluetooth problem, it was at least partially due to a Bluetooth driver error. However I still need more feedback on this issue.

Working good, like the new NMEA live display, had problems swithching back to NMEA though, could be my BT-338 and the SBAS tab returns a 168 error.

Could it be the problem with switching protocol and baudrate at the same time I have read about? Is it common? Maybe I should add switching of baudrate in both protocols and only allow switching protocol without changing baudrate? Are SBAS Set commands accepted? It could be that message 168, Poll Command Parameters, is not supported for polling message 170 SBAS on GSW3.

Hmm, I get a 168 error trying to get sbas mode's with my haicom hi303iii. I wonder if this is the reason why sirfdemo also has no poll nav parm feature working too.

No, 'Poll Navigation Parameters' is Message ID 152. Try using a higher baudrate with SiRFDemo. Or turn off some output messages if you are on a fixed baudrate. The response to poll commands are not of high priority so is difficult to get when the communication throughput is too low.
Message ID 168 is 'Poll Command Parameters' which can be used to get parameters for a handfull of messages. SiRF docs says it should work for Message ID 170 'Set SBAS Parameters' It works on GSW2 but it doesn't seem to work on GSW3. In the latest version of SirfTech I try an additional command Message ID 166 'Set Message Rate' but I think you probably will get negative acknowledgement on both.
