I have had to use my map a few times already when the GPS provided erroneous data, so I only trust it when it sounds like it's being honest with me.



What kind of erroneous data did your GPS provide? Maybe you were being jammed by the Ruskies.

Haha, well first for whatever reason it did not show the last airport in my list of turn points/landables even though it was programmed, so I had to pull out my map to find it.

Second time, it lost GPS signal and told me I would arrive 5000ft low to next turnpoint, which was impossible, I was only 6 miles away at 4000AGL. Eventually my GPS figured out where I already knew I was.
