When I installed my new Helix 10 with an external gps puck and heading sensor, I put it where my old 999 puck was. Of course the old one did not have a heading sensor. The Helix will show the arrow for my heading correctly with the boat showing at about a 45 degree angle, not in line with the arrow. Tried to align it according to manual to no avail. Had a guy tell me it was interference from being too close to outboard motor. Has anyone else seen this? Should I move from current spot to corner away from motor as shown in picture? Wanted to ask before I drill two more holes! Attachment 331936
