Do not know if anyone has tried this yet, have not seen any topics on this yet...
I have recently gotten a new computer, and a new usb broadband 'stick'.
I knew that the broadband 'stick' from my phone provider had GPS capablity, that's what the package said.
I have installed Microsoft Streets & Trips 2009 into the new laptop, and with the provided Pharos GPS 500 anteanna, everything was working fine.
Being a tinkerer, I figured there should be some way to use the broadband device's GPS for Streets & Trips. Just turn on the GPS on the device in the device window, and enable NEMA.
Then go to the S&T screen, click on the GPS button, and hit "Configure GPS" button.
Click on 'scan' to look for the comport, click on the port with the device, then start your GPS tracking.
I ran a trip 350 miles through west Texas with just the broadband card's GPS, and did not have any problems with routing. The altitude was about 90' differnt than the actual altitude, but close enough for me!
Using a wireless broadband card like this eliminates having another USB cord plugged into the computer, or if you lose the access to the standalone GPS antennea.
