Default Garmin auto pilot issues

Alright i have read all the post and it got me thinking about my heading issues.
I decided to take a compass and check the heading sensor location again,since right behind it are the 2 starting batteries..
Well as expected there was interference,so i moved the compass down to the floor and it went away and gave the right heading according to my dash compass..so i moved the heading sensor and while it did change it never did match the dash compas or the handheld?

I have not redone the setup wizard yet but i will try that in the am..

I did notice a 10 degree difference with the engines running?verus when they are off?

The other thing,the auto pilot, the dash compass nor the garmin screens never read the same while in the slip,is there a way to make sure the 4210's are reading the heading sensor?

Any help advice etc will be appreciated it is way to hot for an old fat guy to climbing in and out of the console😂😂

Do the setup wizard and report back to us, I believe that you will be much better off afterwards.
Is the heading sensor showing up on the network?

Change the data box on the plotter to heading. It'll match the pilot. It's probably showing cog. Which is useless when not moving. But it's good to show both. Heading and cog should be similar while moving. That allows you to check.

You defiantly needti swing the compass and set north. If you moved the compass. If it changes 10 degrees when the engines run. It's likly still in a bad spot.

There is options in the setup screens to set the compass heading. But as Mike said first do the setup where you drive in 1.5 circle. That gets the compass to know the orientation that it is installed. I had to run the setup a few times, All but the first time I skipped the run north part, and just set the heading manually while on lift. Now my compass and my Garmin are always within 1 degree.
