K&S,
We recently installed the Northstar M84 multifunction display with a 2kw radome and the fish finder transducer. We had installed the Navman instruments three years ago and have not had any problems so felt comfortable going with the Northstar Explorer series equipment. We also installed the VHF 720 with the remote microphone and like both units very much. The buddy track feature works great. We also installed the Sitex AIS Engine which integrated nicely with the M84. We had a few installation hurdles and Ron at Northstar's technical support was of great help. He was able to answer all our questions and provided some tips on the installation.
Almost all of our equipment, including the autopilot are either Navman or Northstar equipment and so far so good.
