You can even find ones that imitate the original Navigation module, like the one from Erisin. But making your solution using credit card-sized computer with original controls and displays will provide all the functionality of aftermarket components while keeping the original dashboard layout and retro look.

If you have Navigation module and want to use the original display, you can try OpenBM. Understanding how the electronics works becomes crucial even for simple things like resetting service intervals or erasing CAN errors. The core of car communication is a bus line - two-way serial communication line, with one or two wires for the signal. All cars have multiple bus systems that group electronics depending on their use in the car, like CAN-busI-bus, K-bus, D-bus, etc.

We will focus on I-bus Information Bus which is used to control radio, CD, navigation, interior lights, parking sensors, steering wheel buttons, etc. I decided to put in Raspberry PI 2 as a media player but use all original displays and controls already present in the car. Since the CD changer unit works only with audio CDs and is already using I-Bus protocol for communication with other devices in the car, the obvious choice was to replace it with RPI and put RPI in the trunk in its place.

Beside RPI itself, we need a power supply and a device for connecting to I-Bus line - and of course, a car. I dismantled it and connected wires directly with some soldering. You can use other solutions also, as long as the input is 12V and output is 5V 2A at least. It is cheaper than Melexis TH but I had problems with sending messages and abandoned it as a solution.

Here are the settings used to configure serial port to work correctly connected to the I-Bus network:. I picked Wheezy distribution because we want to cut down boot time to the minimum and keep it as small as possible.

Since Wheezy is obsolete now, you can use Jessy. Both will fit on a 4GB SD card. We will host our app in Node. Messages on I-Bus are sent as bytes with no end-message flag, so we need to parse all received bytes and try to compose a message from those, calculate hash and use the last byte for comparison.

Here you can find the description of the I-Bus message format. Luckily, Osvath-Boros Robert developed node-ibus plugin that allows us to send and receive messages to and from I-Bus easily. As a startup project, we will use node-ibus-mediacenter - thanks to Robert. For the media player, we will use MPlayer which supports command line interface and can play all known media formats including online streams.

As a wrapper around MPlayer, we will use node-mplayer plugin. The idea is to use MID buttons to navigate through folders with our media, start playing media, fast forward and reverse through the current song, and use the steering wheel buttons to skip songs back and forth.

Also, we want to use all 20 characters of the MID display - not only first eight, but also all others that are normally used by the board computer. To do that, we need to mimic CD changer behavior. Note: We keep all messages in the messages. Feel free to modify those to support your units.I Have newest MCU 1.

Not just door locks, but, turn signals, sunroof, windows, dash lights and the list goes on. I just tell them that it might be a problem with the K-Bus, which usually makes them more confused. Since these problems can have any number of causes I can't help diagnosis it over the phone or through emails. I decided to create a starting point for people to learn a little about the K-Bus. The letter number preceding the control unit is the module number. The best place to troubleshoot problems with the K-Bus is to first measure the voltage on the bus.

If the bus is sitting at anything less than 12V then something is stomping on the bus pulling it low and not releasing it. The best place to do this is at the X connector block which is located above the fuses in the glove box. See picture below. All the K-Bus devices come together at this block. The wire to each device can be pulled off individually.

Edit: Everyone would like the answers first right? Values just cycle from 0 to FFFF then start over at zero. Fuel consumiption is the rate of change. Multiply by 10 and that is Odometer in Km] -B2 is fuel level. Full being hex 39 Fuel light comes on at hex 8.

One could also be built from bare chips. Project detail: What we really need to do is "reverse engineer" the can bus messages on the E Many people seem to call this hacking. Reverse engineering can bus messages has been done on several cars and there is software and hardware available to make the process easier.

First step of any project. Here are some links to some of the information I found the most useful. Many others may match as well] Reverse engineering by DIYers has been done on various cars. I attempted to communicate with my E46 a few weeks ago.

Wish I had the car handy to try again. Not specifically needed for can bus hacking but is interesting on the engine swap side of things. And I'm havin a hard time holdin these alligators down!!!!!! Just the detail of getting started. Ok so first step is research. Me being me I skipped step one for the most part and started with buying hardware and trying things.

I bought a "can bus shield" from spark fun.

Why this hardware? A guy that knows more than me recommended it. I was busy and wanted to skip some of the research part.
