Minnkota (to Me) has always been helpful. I've called them from the middle of the lake.
Call their Tech Support, make sure you have GPS signal...good luck.

mine didnt work and i discovered that the gps puck had no power. powered and spot lock worked.

The grounds in the wiring on boats are so often a big problem. As with a vehicle, we have a chassis ground, boats there is no such thing...

Thanks guys for the your help
