Is there / will ever be any difference between 2d and 3d version of NS430?

Apart from the 3d version being integrated inside the cockpit and linked with electrical system of the specific plane, are there or are planned any other differences between specific 3d and common 2d version of the module? I.e. integration with existing radio systems or dialog with other navigation instruments (i.e. HSI, heading knobs and such) for the 3d version?

2D is like a separate window inside of DCS that allows you to control it. 3D is the exact same thing, except the only difference separating the two apart, is you have one quite literally modelled into the cockpit.

In a simple Cesena C-172 you can choose to navigate using VOR, and then your radio bearing indicator Arrow is linked to VHF and points to the receiver, in addition you can also set your selected course in it; orherwise you Can navigate using GPS and your cockpit instruments uncouple from VHF and link with GPS. Is something similar planned for DCS? In Uh-1 for example we have an instrument showing VOR bearing and course. If One day we'll have ns430 for uh-1, Will this instrument be linked with GPS or Will It Be completely Independent? And what about future upgrades to actual l-39 version?
