Running software apps on a display screen

[BBPanel]

Building street rod (56 Chevy Panel) and would like to have a decent sized display screen with some of the functionality that we have in newer cars. Would I be able to run Android Auto (specifically for Google Maps) and XM radio? I might also like to access HVAC controls via Restomod Air's bluetooth app.

So some questions to get started. Is Android Auto proprietary and applicable to a specific vehicle or can anyone run it? I assume an external XM receiver would be necessary but how would one interface with it to display controls?

I'm sure I would need a "smart" device of some kind - what would you suggest? Obviously it would need to be bluetooth capable. Maybe all of this is not easily done with non-oem hardware/software.
A lot of questions but a place to start - I tried a keyword search to get some ideas but I guess I wasn't using the right ones. When it comes to electronics I'm a novice at best.
