GTNxi 650 in C172 MSFS202

[jmtkelly]

I am new to the simulator world and am trying to replicate the setup of a plane I
currently rent at a flying club that includes a GTNxi 650.  I am using MSFS2020 and
am interested in figuring out the best way to get the GTNxi 650 into my simulation
environment.  I am wondering if I purchase the TDS GTNxi Simulator if it will work
in a MSFS2020 plane that does not normally have this piece of equipment. I am also 
wondering what most people here do for controlling the touch screen:

ie Do you just use you mouse to interact with it OR do you use RightSimGear hardware
with this?

Looking for advice.
