It would look out of place. the idea of this design is that it 1:1 replicates the look of the OEM front design so it looks factory finish. That's why I chose the Erisin one because the button design is the same shape and style of the other console buttons and back in 2016 they didn't have the Avant 4 that was mechless like they are now so no disc slot.
Android Auto wirelessly is what I want because of convenience. No need to update apps on another device then, just everything from phone working seamlessly with the option to also load apps up directly on the unit (currently what I do anyway) where needed like with Netflix, console emulators etc.
My first Android unit was a Parrot one with no side buttons and it didn't look right. You can also get full all screen models etc but they all look out of place. Has to be the amber lit buttons with buttons in the OEM shape and style.
The physical buttons can also be remapped so your homescreen can be completely clean like what I have now or display a "dashboard"
