Default garmin radar overlay not aligning with 3d chart

Wondering if someone can point in the direction I need to look at... get it...

My current issue is this - when looking at the map in 3d, with the radar overlay on, the radar does not match up with the map. It never seems to rotate when the boat turns.
When looking at the radar overlay map everything lines up perfectly! take a look at the following two pictures... any thoughts how I can reset or make a setting change to the 3d map to allow the radar to be more percise?

You don't have heading? Surprised it works on either.

A heading sensor is always suggested for the most accurate overlay data. I'm surprised it looks as good as it does in the first image as well
