Thank You. I look forward to trying again this weekend. Randy

I have a iPhone 4s. I am not using any thing with it. I do not think the GPS is working even when I am trying outside the car. Thanks for your help. Randy

I do not think I am getting a GPS signal. The bars stay yellow and do not change. When I go to the satellites page I get no supported NMEA device connected?

I am thinking this is why the unit did not work at the track, Randy

I to am looking for some thing I can print and reed through wile I am trying to use the app. Please post when this is available.
