Hi,
I have an iPad2 3G (with internal GPS). I have been using iFly for the last couple of months. The application is stable when no external GPS is connected to the iPad. Occassionaly, I use the Dual XGPS150 (bluetooth) for reliability. I suspect that it induces application freezes in flight. On several occasions, while the external GPS was connected, the sectional map froze, and I was forced to close the application, unload it and reload it.
In addition, sometimes when I connect the external GPS and load the application, there is a 'No GPS signal' warning message, although the GPS receiver is on-line. I am forced to reload the application in this case as well.
Regards,
Daniel
