GPS heading sensor antenna

[TDHcrappiemaster]

I recently installed the new GPS antenna with the heading sensor to get rid of the doughnut.
When I installed it I made absolute sure that the arrow on the puck is facing to the front of the boat however on the screen it has the boat at a slight angle and I want to fix it with out moving the antenna.
Is there a way to correct it in the settings???



Thanks!

There is a heading offset setting under the Nav tab in the main menu...

Where do you have the AS GPS HS antenna installed...??

It is possible you may be getting some magnetic interference from nearby TM magnets or big motor interference...

The easy way to check for this is to position a small handheld magnectic compass over the AS GPS HS antenna and watch the magnetic hand for discrepancy movement...

If the AS GPS HS antenna is getting magnetic interference...it will have to be moved...

Thanks Rickie.
I have the puck mounted on the bow of my boat where my old one was. I will first make the adjustment on the heading offset and see if that helps.
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.
