Cheap android friendly double din suggestions?

[Danith]

I want something that will link up to my phone to make hands free calls, charge my phone via a dock (if possible) and have sat nav and the option to add a reverse camera (cos I'm lazy)

I'm way out of touch with ICE and tech so haven't got a clue anymore

Anyone suggest anything sub 200? Are the eonon chinese things up go scratch?

Also whats the crack with double din if its not a screen? Whats the point of that? Some just look like fat head units with more flashing lights
