will this work for the non-nav?
and 8.4?
Short answer is I don't know.
I know this works for nav on the 12 UC5.
It's actually running Android so it's very possible that you could install it on the 8.4 as Android should properly display on pretty much any screen size. Nowhere in the files do I see anything that determines this is just for the 12 inch.
Looking through the files the only thing I can see that matters is it has the word Harman, so this might only be for people with the Harman system? It's also possible that ALL units contain the Harmon software\drivers or whatever and only activate if you have that system. But it also says Harman Anti-theft so who knows.

Could go to the dealership and take an 8.4 without nav on a test drive and just put this in and see what happens LOL. If the Carmax nearby had one I would gladly go and test it out.
