leave the gps off, 
Amen brother well said.
You need to map read, as 438 mentioned look at the big picture of ground features.
We never employed wallys who leaned heavily on GPS (Regularly umplugged them on new recruit check flights
to see if they had the mustard!) GPS NPA's (GNSS) are a different thing. Just take the opportunity to grow from this
Granted it sounds like a new 172 with the "good gear" but if you can relate to ground features, this will save your toosh in a jet, turbo-prop or piston 1 day, mark my words.
