Default AIS indicator pointing wrong way

Hi - I have an ICOM 506-21 on my NMEA 2K along with a Garmin 1040XS. The problem I have is that the triangular AIS vessel indicator is pointing 180 degrees the wrong way. Spoke with ICOM and GARMIN and still cant figure it out. Wondering if anyone else ever experienced this?

Is your boat position/heading on your GPS also pointing the wrong direction? Have you tried re-calibrating your GPS Compass Heading? Any possible magnetic interference?

What do you mean. Every other boat (ais targets) is backwards?


or your own boat is backwards? Which is nothing to do with ais.

Hi - boat position/heading on my GPS/ Chart plotter is spot on...

Hi All AIS targets on my MFD (depicted as triangles) are pointing in the opposite direction of the way they are actually travelling. Yeah AIS targets going backwards...
My vessel icon is fine, pointing at heading or COG, wherever I have it set.

I was thinking that if the ICOM 506 was set for north up and my MFD was on COG (or the other way around) maybe that could be the cause but ICOM said that shouldn't matter, that the AIS receiver is just putting raw data onto the N2K.

Recalibrate your thinking and just remember that the triangles are backwards... boom problem solved.
