On the hunt for a decent double din head unit

I want one that looks as OEM as possible, without the flip out screens and all that

I'm currently looking at the Pioneer AVH-2400BT

My budget is around £250 and i only need something basic with the usual USB, AUX and look smart (bluetooth would be a bonus but not essential, same with touchscreen) but it does need to be good quality at the same time.

Any recommendations??
