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
Connect IBUS USB adapter to BMW (using 12V, GND, IBUS)
Install USB 12V - 5V adapter (using 12V, GND)
Install Raspberry Pi in the dash (and power w/ 5V from adapter)
Connect IBUS USB adapter to Raspberry Pi via USB cable
Connect Bluetooth USB dongle to Raspberry Pi
Connect Ethernet cable to Raspberry Pi (and wire to glove box)

2. Raspberry Pi
