I have an IFD 540 that I use with an iPad running Foreflight and a Stratus 2s. For the last few flights, I've been getting a notification on the iPad that the IFD has disconnected. It seems that the IFD then reconnects, but later disconnects. Rinse, repeat. I'm also running a Stratus 2S. Is there anything I or my avionics shop can do locally, or does the IFD need to be shipped back to Avidyne for repair? Any help would be greatly appreciated.
