I have an APM 2 and the GPS functionality is not working at all. The blue 3d fix light never comes on, solid or blinking.
When I run gps in test from the CLI i get G! G! G!
The board is brand new and has never been flown, does anyone have any suggestions?

Took a dump of the command like and it does not look healthy:
