Here’s some pics of the AF3500 from Advanced Flight Systems.  Originally, I had decided to go with the engine monitor only, but then the AF3500 was announced, and I thought it looked pretty good, so I put in the order for the combination engine monitor and EFIS.  I thought that it’d be kind of nice, and might suffice for backup instruments.  I received the unit, and needless to say, I’m impressed.   It’s got pages for the EFIS, engine monitor, combination of the two, round oldschool representations of ASI ALT and VSI, and my personal favorite, the weight and balance page.  it’s a graphical representation of the w&b where you can dial in the weights at each station, and see where the CG is and if you’re out of limits.  man, it’s cool.  also, i called and got the map feature for my unit, and I installed it to check it out.  first of all, the version 5 software is pretty cool, a bit of a new look for the pages.  and the map feature, well it’s awesome.  right now it doesn’t have terrain, but it’s got lots of info.  I tried to take pictures of the different pages in the different available configurations.  there’s a bunch of flexibility in the layout, so you can make it be what you want.  also, if you don’t use all the available pages, you can disable them in a menu so it only cycles through the pages you use.  I called and spoke with “Dave the map guy” at AFS before I ordered the upgrade, and asked him all kinds of questions.  From what I remember, he said that they were working on terrain, XM weather, and autopilot integration.  it’s gonna be awesome.  For my setup, i’ll have one SL30 hooked up to my Chelton, and one SL30 hooked up to the AF3500.  Also, the AF3500 will supply engine and airdata to the Chelton, and the Chelton will also output GPS and flightplan data that can be displayed on the AF3500.  I haven’t tested it yet, but it should all work.  Talk about integration!  So i’ll have two extremely capable systems in the aircraft, and while they’re highly integrated, they’re completely independent.  Also, I ordered the AF3500 with the built in internal battery.  What a super unit.  oh, I think the coolest feature about the map stuff is the airport info pages.  when you select an airport, there’s a few pages of info.  it’s got things like traffic pattern altitudes, and there’s a little picture of the runways, with an arrow depicting left or right traffic.  as you step through the runways on an airport with multiple runways, it highlights the runway that it’s currently showing info about.  also, there’s the remarks for the airport as well.  it’s like having an airport facility directory (AFD) right in front of you.  I tried to take the best pictures I could.  they’re kind of crappy, but they give the general idea.
