Map Orientation View

I like to keep my top 540 in Track Up Centered view with the aircraft centered.  I know that you can toggle through the different views by pushing in the bottom knob repeatedly.  Sometimes times when I start up, the 540 is back in North up view and I have to toggle it back to Track Up Centered.  Has anyone else seen this?  It happened again today and now that I think of it, I also did an update of the Nav Data and Obstacles and had to push in the bottom knob to select those options before starting the update.  Is it possible that pushing in the bottom knob to make selections when doing an update, would also change the desired map view (since it is the same knob action)?  If not, what might the cause be?

It happens to me occasionally to me as well.  I've never been able to determine why exactly.

Just curious, when flying IFR, what view do people prefer? I've always flown with Foreflight in North-Up orientation. However, on the IFD440, I think I prefer track up, with Land and Nav Data turned all the way down.

What do others prefer?

Yes,   When it changes to North up, it stays that way until I toggle it back to Track up.

I would have to check the Track value when it doesn't revert to North up and I do move the airplane into a hangar after it is powered down but it is basically just pushing it straight back so it is roughly on the same heading it was on when powered down.  Also, this change sometimes happens when I am just parked outside after making a flight and starting up again later the same day in the same spot.

Mark, to change the map orientation, you need to push the bottom right button.  It will cycle between North Up, Track Up Arc, and Track Up centered.  The Aux user setting only changes between Track and Heading mode for those three views.

Duh.... I figgered it out today... Push the right lower knob and the view changes. I'm a happy camper!

When I was having issues like this, it was because my DG provides heading info to the 540.  (When you turn the DG knob, the 540 map rotates).  

So, your saying that if it's in Cursor Centered view, it doesn't automatically index to the next waypoint and the map doesn't rotate if in track up mode. If so, that would explain the behavior.
