I actually fly 496MA and it is equipped with a G1000. I also fly out of KFRG. This airport is almost impossible to find at night but with the G1000 you should be able to find the airport, or at least know when you are on top the field.
Also, there are jets at SheltAir but they are far enough away that you can get past them and taxi to the delta hanger. I don't know what he was looking at.
He was the most chatty pilot I have ever heard. He seemed to be clueless about what was going on.
Getting lost in VFR with a G1000 then having your problem broadcast on the internet...
