Understanding Route Info

Rather than showing the usual, normal route fixes and air routes, I noticed simply “3707 07629” on the Route line for a Citation X flight between Quad Cities and Williamsburg. What does this mean? Thanks.

Either 37.07N 76.29W or 3707’N 7629’W, I forget which.

Looks like it’s probably N37 07’ W76 29’ as those coordinates are about 1.5 miles from KPHF (Newport News, VA), and N37.07 W76.29 is in between two different airports - 11 miles from the nearest one.
