looking for some direction, on a 7" remote touch screen to use with galaxy S4
looking for some direction/input on trying to accomplish the following.
I want to flush mount a 7" to 8" touch screen in my car which will allow me to control/mirror my samsung galaxy S4. I currently use the s4 daily for navigation & to stream music using spotify, but would love if I could display the navigation on a larger screen (7" to 8") which i plan to flush mount in the dash. If i could also control/use spotify from this same 7" to 8" touch screlen that would be an added bonus.
From searching i can only find stuff on mirroring the s4 display on a TV, but not a touch screen.
I do have a kindle fire hd which i won a while back and never use, not sure if it could be used as the touch screen for what i am trying to accomplish, if not I have no problem buying a screen.
Any input/suggestions would be appreciated
