Narrative:

I put the wrong coordinates in the GPS (1 digit off). I navigation'ed to the wrong airport at night. I was too low on fuel to spend much time sorting out the problem once I noted my mistake. Given the situation, I landed at the nearest suitable airport (because of my low fuel state at night) to sort out my navigation problem. It was after I landed that I figured out the GPS problem. The contributing factors causing this situation were: 1) a new airplane with a navigation GPS and mfd I was not thoroughly familiar with. 2) not knowing (trusting) the airplane fuel gauge's accuracy well enough. Solution: I should have been more familiar with the navigation system to perform the checks necessary to catch the problem before it occurred.

Title: C172 VIOLATES CLASS D AIRSPACE BECAUSE OF GPS NAV ERROR AND LOW FUEL.

Narrative: I PUT THE WRONG COORDINATES IN THE GPS (1 DIGIT OFF). I NAV'ED TO THE WRONG ARPT AT NIGHT. I WAS TOO LOW ON FUEL TO SPEND MUCH TIME SORTING OUT THE PROB ONCE I NOTED MY MISTAKE. GIVEN THE SIT, I LANDED AT THE NEAREST SUITABLE ARPT (BECAUSE OF MY LOW FUEL STATE AT NIGHT) TO SORT OUT MY NAV PROB. IT WAS AFTER I LANDED THAT I FIGURED OUT THE GPS PROB. THE CONTRIBUTING FACTORS CAUSING THIS SIT WERE: 1) A NEW AIRPLANE WITH A NAV GPS AND MFD I WAS NOT THOROUGHLY FAMILIAR WITH. 2) NOT KNOWING (TRUSTING) THE AIRPLANE FUEL GAUGE'S ACCURACY WELL ENOUGH. SOLUTION: I SHOULD HAVE BEEN MORE FAMILIAR WITH THE NAV SYS TO PERFORM THE CHKS NECESSARY TO CATCH THE PROB BEFORE IT OCCURRED.
