[Q] Android Car Theme/ Skin

Hey Guys,

I am looking for advice on the best Android options (custom rom, apk, skins etc) for an in- car device I am trying to build. The device will run Android and connect to a smartphone for data and notifications (like Android Wear). I would like for it to have the following capabilities, without touch input/ voice only :

Device Capabilities/ Characteristics:
- minimal UI
- Basic Phone Functions (make calls, reply to sms, and get directions - all without touch input)
- A few select Car apps, from the Play store Apps (the issue is navigating the UI without touch)

A few options I've tried:
- Google Glass apk (issue: buggy, no play store apps)
- Google Now (voice commands), with Launcher (UI), Tasker (custom commands) (issue: navigation of UI, smartphone connection)
