- Add an Aux-In or music jukebox
- Remap steering wheel buttons
- Remove the Nav warning screen
- Display text like emails and SMS on your Sat Nav, radio, or dashboard
- Access engine and performance data like air/fuel ratio, oil pressure/temp, and VANOS
- Code retrofit parts like rain sensors, run-flat tires, theft alarms, and keys
- Access the proprietary error logs to troubleshoot engine, transmission, or accessory problems.
Continue to the next step and I'll answer a few questions, then I'll show you how to build your own.
Step 1: What is it?
The Car Kracker is a microcontroller with a bit of hardware to talk to your car. It plugs into a connector in the trunk and has several default modes built-in;
- Audio Jukebox Mode: Play music stored on an SD card
- Advanced Diagnostics Mode: Remove the Nav warning screen, access error logs and read / modify ECU characteristics
- Bus Sniffer: Display data traffic and send test packets
- Audio Aux-In Mode: Enable Aux input to stereo headunits
- Traffic Camera Alerter
- Automatic Audio sync
- Auto Unlock: Unlock the doors when a specific Bluetooth device comes within range
- Data logger + phone home: Automatically send car location and speed via SMS
The Car Kracker works with the following cars;
- 3-Series, 1998 - 2007 (e46)
- 5-Series, 1995 - 2004 (e39)
- 7-Series, 1994 - 2001 (e38)
- X3, 2004 - 2010 (e83)
- X5, 1999 - 2006 (e53)
- Z4, 2002 - 2008 (e85, e86)
- One / Cooper / S, 2001 - 2006 (r50, r53)
- Convertible, 2005-2008 (r52)
- Range Rover, 1999 - 2003 (L30)
Unless you want to update the firmware on your Engine / Transmission, It's pretty much impossible - the data bus is designed so that errant / malfunctioning devices don't break anything. Changing preferences (like turning off the door gong) just updates the settings memory, the firmware doesn't change.
The Car Kracker builds on many people's work - Many thanks to Dr_Acula for respinning RS232, Jochen @ Navcoder, the BMWCoders forums, Rayman for audio playback, e46fanatics, and bimmerforums. Thanks Everybody!
