AIS 650 problem when using auto pilot

[HiViet]

Hi Chuck

I got the AIS problem fixed. I had both NEMA0183 and N2K connected to GPM400. I removed the NEMA0183 and problem fixed.
I found that this problem not only happen when AutoPilot engaged track. It also happened when Radar engaged tracking as well.

But problem fixed after removed the 0183.

As for the VHF Ray240 not report DSC problem. I removed the Seatalk1. I'm waiting for some one to hit their DSC button. It may sounds bad as they only do the DSC during emergency. I may have to wait for a long time until some one do so.

Is there away to check to see if the MFD receives data from Ray240 VHF?

Thanks
