Any decent Android head units?

[R E S T E C P]

Do any decent Android double-din head units exist?

I can only find nameless Chinese units with dubious reviews, or the Parrot Asteroid which may as well be a proprietary system as it takes away all the features I want from Android like the app store, customisation, etc.

I'm not looking for Android Auto - I don't want to plug my phone in - I want the head unit itself to operate on Android.
