Re: anybody experience with KING KLN 89 & KLN 89B GPS SYSTEM
Lots of experience in the 89B, 90B, GNS430 and even Glass. For the price, you can't beat a 89/90B. Either of these units are great for easy navigation and RNAV approaches. Like stated before, it's very simple logic. It's good for getting information about where you're going, but the map lacks something to be desired. Nevertheless, it's easy to use when you get used to the Chapter-Page logic of operation, and you can always do Direct-To functions with the NDB, but it won't allow you to do an overlay. If you take the time and can input waypoint fixes, that works, or assisting your guidance with using the OBS function with the NDB.
SHort story long, I have liked it. Go for it.
