here's what i did (copied from a previous post)
Ok, you need a copy of the latest SirfDemo.exe. Open the program and its gonna ask you to select your com port and baud rate. Your defaults should be already listed so just hit ok. Then you'll have to hit the connect button ( little button that looks like two wires unplugged). From there go to Action/Synchronize protocol and baud rate . After you hit that look on the title bar and it should do some testing with various baud rates. It should stop on 4800 (the only one that works with our GPS). Click save. Click ok.. exit program. On the way home from work (before i did this) the most sats i had was 3. On the way to work today (after) i averaged 9. Also seemed to speed up the time it took to display to iguidance. Hope it works for you!
Do this, if your sats dont improve there may be something wrong with ur gps.
