smartphone controlled headunit

FrancoPhoto

hey guys,
I'm looking for a head unit that is basically controlled by my samsung s5.
i don't need navigation , id like to use google maps from my phone but be able to see it on the screen of the headunit
i also just need bluetooth so i can stream my spottily app for music.
being able to view videos on the head unit from my phone is a plus .

i think mirror link is what i need but i can't get a straight answer as to what mirror link is

any help is appreciated.
