We have this same set-up in several of our United 170's. At first I was excited to have them but after using them for several months, I would definiately prefer the paper jepps. The airport diagrams are very cluttered and hard to read unless you zoom way in. There is no moving map on the a/p diagram (at least on ours). There is no briefing strip on the approach plates, much harder to brief in any sort of organized manner. The arrival charts are also harder to read. They can't be read during the day without the sun shade pulled up and are too bright at night, even in night mode. Also, ours are broke most of the time...hopefully you guys will have better luck. On the brighter side, I now know several vor names that I didn't previously.
