Set your NMEA and baud as described.
Plug in your GPS unit and make sure the programe is running on your lap top, go to Options on the screen of you lap top and click on GPS settings, click on
test on the small screen it should
test the link between your lap top and the GPS and tell you if it able to detect the GPS.
If it is not detecting the GPS then something is obviously wrong.

Eric,
are you using one of those USB to Serial conversion cables?? - I've had strange results with those.. The major issue has been that for some reason (after it has been working for a while, that all of a sudden it can't find the com port any more) - looking in the system config under hardware, the "virtual" com port which has been created (ie com5) is no longer there, but com6 is.. You might want to confirm that side of it.
Also, when using the Track On feature, it works fine at speed, but loses the connection when I stop - but not consistently!! Frustrating
I blame the USB-serial cable
Good luck

Eric,
I have shared your frustration. I work for CFA, and set up a vehicle based fire mapping system to plot fires and mark water, hazards, losses etc...
In setting this up they gave me an Acer Tablet (touch screen laptop) garmin GPSII, and the dreaded USB adaptors. We have come the the conclusion that the use of the USB port is just too unstable and unreliable.
I have used electronic
GPS mapping and
navigation for a few years now, and I'd only reccomend serial connections. I am however about to investigate the use of Blue Tooth
GPS's, (in the next week or two) I am hopefull that this will be more stable and allow the connecttion of a
GPS to a laptop which does not have a serial connection.
Sounds like you have got the settings right, but without looking at it... who knows ?
I am in the eastern suburbs of Melb, if you are out that way, I'd be happy to have a look at your set up, and am happy to show you what I use.
Cheers
Daryl..
