2004 342 Northstar Radar saying "Radar offline"

elangone

I have a 2004 342, with Northstar 6000i GPS/plotter/Radar. recently the radar stopped working, giving me a "radar offline" error message. I've checked and the radar control box is getting power, and the fuse is good.  Does anyone know if there are fuses in the actual radar antenna? have any other troubleshooting suggestions?

thanks in advance,
Ed
