After a lot of faffing and half a day in the office spent surrupticiously meddling with it I got Inflight working on my Ipaq 5550 and BT-308 GPS. Is there a minimum signal strength? I had problems getting a consistant connection - the GPS was quite hapilly paired, and I could see it was connected in GPSUtility and getting data and position info but it took *ages* for Inflight to recognise the fact that there was a GPS connected and occasionally dropped out for no real reason...Is there a minimum required satellite strength to get it to work properly? The ariel was up against a window facing a wide open space and was only a meter or so away from the PDA...
