BMW E46 - Android, Raspberry Pi, IBUS Controller

IBUS interface for my E46 BMW written in Python & Java. This is to be used with the IBUS USB interface which can be acquired from Reslers.de, or from Amazon/eBay.w

Overview

There are three main components of the solution:
Android Tablet - Primary front-end device for interacting with the car
Raspberry Pi - Mini-PC that handles communication between the IBUS adapter and the Android device
IBUS USB Adapter - USB adapter that provides USB/UART interface from physical wire in car

There is also an Android Wear (4.4W) component that allows you to control your vehicle from your smart watch!
Android Wear Device - Secondary device that provides quick interactions with the car

Pre-Requisites

1. Car Installation

Remove OEM Navigation Head Unit from BMW
Tap the 12V (red) wire, the GND (black) wire, and the IBUS (red/white/yellow) wire
