Installing AS GPS HS antenna and confused.
directions for calibrating heading sensor calls for going into menu to "heading offset" but the offset is 0 to 30 degrees.What if its off the other way.Haven't done the step using satellite positions while moving in a straight line.Have boat pointed south( in garage) and heading sensor is pointing at 190deg.If I try to calibrate using menu option, I can only go from 190 to 220deg.I need to go from 190 to 130deg.(opposite direction) To bring it to 180deg.
using version 6.61 on hb798ci
antenna puck is point toward front of boat.
Used another compass in different locations and doesn't seem to be any strong magnetic fields with various equipment on.
