Details off another forum,
The old Garmin boxes could do all of these things except for the colour and NVIS compatible displays.
I think the main feature is the smaller vertical space. Often upgrading from a GNS530 to a GTN750 can be vertically space challenged.

Yes, exactly, although Trig’s TX56/57 is equally thin.
The thing I find funny is that a decade after everybody was moving into “glass”, Garmin realise that there is a big market for separate boxes 
I predict that their next product will be a slide-in KX radio replacement, or a slide-in KLN94 replacement which does LPV

These are two separate divisions within Garmin, each with own development plans.

I think a slide in KLN94 / 89b replacement is unlikely , there are not a lot of those units about as it was outsold by the Garmin GNS units despite the Garmin pilot interface being far worse than the King unit.
Most of these units got replaced in big upgrades that replaced a lot more than the KLN 94 / 89b.

“Glass” really only means that you have a display screens. You can either have an integrated system (e.g. G1000) or a system with separate boxes (e.g. G3X). Both are “glass”.

The G1000 glass in the cockpit is just a control head for a bunch of separate boxes mounted in the back of the aircraft. So little has changed apart from the place you put the separate boxes and how you control them be that remotely or from the front of the box.

I know, but the G1000 is an integrated system. You have the GDU and the GEA etc. which can only be used together. You can’t just hook up e.g. a separate NAV box to the system. In contrast the G3X is designed to work with a variety of other avionics boxes.
