I have been using my AF-3500 for the last four years, connected to a Garmin 496. Until today, the nav data from the 496 would show up on the EFIS screen when a waypoint was entered. Today, when I entered my home field as a direct to waypoint, the bearing line showed up on the EFIS, but not the pink course line or distance data. Any thoughts on the partial loss of functionality?

I'm also having problems with high fuel pressure readings. We replaced the last fuel pressure sender a few months ago when the same problems occurred, but the new sender seems to have the same problems. The pressure reading goes back to the normal, lower level if I turn the electric boost pump on. Once again, any thoughts?
