What program are you using to start the GPS? The radio shouldn't be a problem. I use the same radio om as you, and I am on VZW. Go to Start>Settings>Connections. You should see GPS Today I think is the name. When it opens hit Open Port. Then I think the other button below says Start test. Use that and see how long it takes. I can use it sitting inside my house and lock within a minute on 5 satellites. Use that to "prime" the GPS then open your preferred GPS software. You have to close by going to menu>quit. Hope that works for you too.
