If your not interested in trying to find a place to put that lil screen, I think the dice media bridge does bluetooth and supports streaming. I'm about to start looking into it, my old old old old dice unit has gotten so noisy. I was considering a Dynavin, but I'm going to wait. The Media Bridge seems like a good "patch" for now...
If and when I do, I'll have a used parrot kit for sale...
