I'm having a little difficulty getting the Navigator software to find the GPS device.  is there any documentation on the expected baud rate, and format of the gps data?

When I start navigator and go to the gps setup area, the com port that the gps is on, usually comes up as "(In use)".  On the odd occasions when its not in use, it does not recognize the data as gps data.

Looks like we've identified the dataset issue, now to figure out the GPS problems.  If you're only showing GGA sentences, that is probably the problem.  A typical valid log will look more like what I've copied below. 

Is there any application that came with the modem that you can use to see satellites acquired, data coming in, etc?  Usually, some freeware is bundled for setting up and troubleshooting purposes.  If not, Franson GPSGate is great for a free 15 day trial.
