That's a Garmin GMX-200
Really ok for SA but thats about it.
I know that one. I fly with it all the time. It's actually very useful for other things like NEXRAD, Aircraft wx radar, and TCAS. I also have started using it for the approach overlay and put the 530 up a different screen (some of that is company training-based).
What I was mentioning was the thing below your transponder. It just looks like an old school RNAV, though it may be something else.
