Helix 7 won't mark waypoints

My helix 7 won’t mark waypoints, has anyone else had this problem? When I try to mark a waypoint it says gps fix required on the top of the screen.

You must have a GPS position in order to mark a waypoint (a GPS position).
Are you inside a structure, house?

Typically, especially with these lower end 7’s and such, you need to be outside with view of the sky for GPS to work.

You can press the VIEW button until you reach a GPS screen, this will show you the GPS is locked on or searching. You may need to enable the view if you have turned that view off already.

Also I think you can use external or internal GPS u need to see ifs its set to internal for the GPS receiver built into the control head and not a deck mounted puck GPS I can use either one on my Helix 7 default is built in. I had mine so messed up I had to go back to factory default and start over.
