The KLN 90B is a popular GPS device mainly found in general aviation aircraft and small commuters. It dates back to the early 90s, but it's still widely used today.
Features of the KLN 90B are:
-Split screen, showing two different pages at once
-Up to 26 flightplans can be stored with 30 waypoints each
-SID, STAR and non-precision approaches
-Enroute and OBS mode
