This is indeed very frustrating because there is not enough "interoperability" and compatibility even within one brand going back or forward.
NK2 is supposed to address this and this may be around for a few years. I would look for an NK2 system, but be prepared for "more of the same".
Aside from all this, the GUI leaves a lot to be desired at this date. When my radar went south I went for a MFD and for a C80 with a 2KW radar. OUCH It was a lot better than the old Vigil and then I started with the charts
, the GPS antenna
I haven't kicked the tires on the new gear
, only read about it and am hangin back until my gear
goes south because at this date I have found that it's more than I had for many years and more than I need in a sense.
I am very happy with a small hand held PDA plotter (iQue3600) in the cockpit
and rarely use the other fixed mount expensive stuff at the nav station. But it's there and standing by.
is a very fragmented industry.
