Windows 10, VirtualBox VM Manager, Ubuntu v16.04 64-bit

OR just Ubuntu Ubuntu v16.04 64-bit as the main OS.

Required Knowledge:

To Run: Ability to follow these instructions, create a Virtual Machine, use a command line interface, and basic understanding of git and bash shell scripting.
To Develop: At least one or more of: C, C++, JavaScript, Linux/Bash Scripting, Android, gstreamer(0.10 & 1.0).

Required Hardware:

Android Phone: v5+ with Android Auto App installed and USB Debugging Enabled.

Part 1: Virtual Machine

If you already know how to do this or are already on Ubuntu/Linux skip to part 2 These are instructions for Windows 10 and Ubuntu 16.04(64-bit) but any recent Mac OS and Linux distro should work just as well.

I hope this will lead to more programmers who did not want to bother installing a new operating system or spend a lot of time figuring out how to set up the development environment and whatnot to contribute to the Android Auto project. I tried to make these instructions as simple, clear, and straightforward as possible but if there are any ambiguities or you have an improvement or suggestion for this tutorial shoot me an email. To all my fellow HaXors out there Happy Hacking!
NOTES: You may need to manually reconnect your phone if it is disconnected by AA. You need to have your phone in MTP mode (you can try PTP as well) to make the adb connection properly. if you are having trouble connecting you may be using an incompatible Bluetooth receiver.
