These are the basic settings for GPA in winmo - I am guessing they are already set, but it is worth a check.

Now go into whatever program you are using and find GPS Settings in the program - turn location on and then look for a com port - set it to com 4 as well. If this doesnt work then look for a "gps intermediate driver" in the same com port list - this lets winmo pick the port itself.

Try these and let me know - Also, I know these are here in some thread or another because that is how I found them back in the day.
