That was what the 690A I was flying this summer had--actually less, since it was just a GNS-400 with the old NAVs and COMs. It actually worked just fine-- once I remembered how to use the GNS-400 (which came back to me very quickly), it was great. I wish it had airways, but hey, you work with what you have.
The Flightstream with ADS-B In made all the difference in the world, though. I'm too spoiled to do without that.
Frankly, a GNS430 with a flight stream and a GDL52 and I’m in tall cotton! It’ll get you about anywhere in the world for as long as the old stuff works anyway. Recently suffered the traumatic loss of the RMI which would have been close to partial panel shooting a DME arc without a GPS back in the day! It’s simply way overdue for an update. Of course there’s no way I can justify a major panel upgrade with clients waiting in line. Good times!
