But wait! There's more .... 
Somewhat hidden on their web page about the Mini feature set, GRT mentions the ability to have weather and traffic on the Mini now. (Cost a few $$ extra for the feature set).
Having done some of the testing on that, I can say that that is pretty cool, especially if your primary screen is an HXr and you run in SPLIT screen mode most of the time.
If you get one, realize that you need to supply ADS-B data to it SEPARATELY from your other devices. That can be either serially (FDS, iLevil) or USB with a hub (iLevil, DUAL, SkyRadar).
The weather data is NOT shared over the serial Display Link (bandwidth) although it is over the "ethernet" link on the big displays.
BUT ... I don't think they mind my mentioning this, a later release will share the TRAFFIC data over the Display Link to a MINI. Just tested that a few days ago.
I fly/have flown with Garmin/GRT/Dynon/Advanced Flight gear in my and other RV's. All pretty cool stuff. But I must say, as a BACKUP or low cost (mini) EFIS, the GRT MINI's are getting harder and harder to beat each day.
DISCLAIMER: I do a lot of testing of GRT gear/features (for free). They are a sponsor of TEam AeroDynamix, which I have flown with in the past.
Thanks for getting some pictures up Widget. I have been saying I was going to do that for a few weeks now.
