I have Simrad
ap25/26 with robnet connected rc36 and ac20 and was very satisfied with ap.
But when I was replace plotter and radar with zeus touch and 4G I have to upgrade rate compass
Added z100 was not enough for marpa and internal gps antenna
was unacurate (maybe instalation in SS box) so I have to add z100 and rc42. Yes I connected it over 0183 to ac20, and I have I plan to connect it in parallel over nmea2000 to function independent from ap.
So far results are very good.
