sounds like a setting issue on either the gnc255 or 4500
I would call tech support from sitting in the airplane
Alan

no the 4500 only displays the map and obstacles-not sectionals and no longer approach plates

gps attitude is not the same as indicated altitude

yes to geo referenced approach plates
no to sectional /airport/low altitude enroute charts(you would have to upgrade to the 5400 for these)
I use foreflight on an iPad mini for these
