yes, you have to be in spot lock to work the jog function!So I wanted to get to the bottom of this and I called Minn Kota technical support. They explained the heading sensor is for the jog feature. If your not going to use jog then the sensor essentially does nothing. I don't plan on using jog so problem solved.
I asked this question on my Texas forum and everyone said the same thing-its for jog only.
