Have you ever tried using Google Maps and enabled the GPS tracking in Google Maps? Would you be willing to give it a try? I certainly understand if you don't want to.
I did find a mistake (mine) in the setup and corrected it. I thought that was why I was getting 0, but after correcting, it still doesn't work. It could be that the GPS isn't picking up the satellites correctly. I will play with a couple things later today.
I have not way to confirm what the GPS is ending, so that is a real problem.
Any help is always appreciated.
Thanks,
Rob
