Hmmm - my radar is skewed 6 degrees from the chart on one screen but matches the chart orientation on the other. I'll go and look again at the settings.This sounds right. I had a bunch of settings dialed in on my 8616 for radar, charts, and combo screens. When I added an 8612 I didn't find a way to send them to the new unit. I had to do through and make manual changes to get them to match up. That included setting-level heading preferences. Until I got that dialed in, the two screens were showing very different heading behaviors.
