I feel that should correct it.
Hi Tom,

I recently installed the heading sensor on my boat as well. Like you I put it in the same place as my old GPS receiver and my boat icon on my 859 is also angled. There is a procedure in the heading sensor manual to check/calibrated the unit. You might take a look at this procedure.

Unfortunately for me I'm getting some electrical interference(prob from trolling motor) and the offset in the unit is not sufficient so I will have to move my heading sensor.
