[Nexus 7 (2013) General] mistr_e:

Sorry I don't have a build log but the wiring is very strait forward and the software I've been tweaking for the past year. I'd love to replace the head unit with this but I'm not super confident of the Wife Acceptance Factor yet.

The audio is wired out of the tablet to a Rockit mic/speaker splitter. Mic goes to an olympus Noise cancelling mic on my visor that works well even with the windows down. Even with loud music I can say "OK Google" and it will pause for my command. The speaker then just goes to the aux in on my existing JVC head unit. Phone calls are also handled through bluetooth on the head unit. Power is through an OTG cable and Anker 4.2a cigarette adapter.

I'm running stock ROM, ElementalX kernel for Fast Charge, Nova Launcher Prime and Desktop visualizer for the main UI. Voice commands are though Tasker and Commandr and gestures with GMD Gesture Control.

Take a look and let me know if you have any questions or suggestions.
