I am slowly learning how to setup and run the MGL iEFIS and it sure seems like I have quite a way to go. In the video linked below, I had an RNAV approach loaded into the 430W and had it driving the MGL autopilot through the iEFIS. As you can see, the autopilot is tracking the command bar but every so often, the command bar absolutely jumps to the right. It instantly rolls over about 30 degrees, then slowly recovers, rinse and repeat. Any ideas?

The second issue is that it would fly to the initial IAF just fine, then attempt to fly the course reversal (not very well, but I'm sure that is a result of not fine tuning the settings just yet). Upon reaching the FAF, the autopilot would disconnect from navigation and go into a straight and level mode while displaying a message in red saying that the HSI wasn't being fed information. The command bar and the two deviation indicators continued to work properly. I tried it twice and got the same result at the same point both times. What am I missing?
