Car stereo head unit to work with Samsung S7 AND Asus Nexus 7 2103 2nd gen in car

[AC Question]

So I want to replace my head unit with one that allows it to talk with my phone and tablet.

I cannot go double DIN and I don't think I can mount the Asus tablet in the car as it is a convertible and the sun will glare out the screen.

Thinking of a head unit with

USB (connection and control)
voice control
Bluetooth
radio
DAB

Please help me
