If you have an EFIS-D10A, EFIS-D100, a FlightDEK-D180, a Dynon Autopilot, and a GPS (probably but not definitely a Garmin portable) that constantly drops from NAV and TRK mode to HDG mode, we want your help.
We're having difficulty reproducing the root cause of the issue here, and so the best way for us to see what you're seeing is to get data from your GPS device as the dropout occurs. If you're a bit technically-minded, here's what you need to do:
------
What's necessary is to tap the TX wire from the GPS to the EFIS.
Bring the TX wire to pin 2 on a female D9, and bring signal ground out to pin5.
If you are using the programming port on your system as the GPS input, a Y-harness can be inserted between the GPS and the EFIS.
The D9 can then be connected to a serial port on a laptop and the data recorded. The laptop you use to upgrade your system will work fine.
A terminal program such as TeraTerm can be used to log the data; be sure to set it to the baud rate you use for your GPS.
Note the time you saw NAVSRC LOST and send us the data log and we'll do the rest.
