You can use the Car Kracker 3 to read advanced diagnostics in your car - you can read and clear detailed error logs for every device in the car, actuate solenoids and valves, and read real-time data Here's a demo of INPA, one of the more popular tools;
Other programs are available, as well. Here's how to do it;
Set up the Car Kracker
In the Kustomizer, begin by setting the default boot mode to 'Diagnostics'
Connect to your car
The trunk connection lets you connect to most computers on the car, but not the engine or transmission. If you need to connect to the Engine or Transmission, you'll need to connect to the On-Board Diagnostics (OBD) port.
There are 3 bus connections on the Car Kracker, they're marked on the circuit board D (Data), + (Power) and - (Ground);
With some spare wire, connect these to your car's OBD port. Older cars have a DLC (Pac-Man) style connector under the hood. Cars made after 2001 have an OBD port under the steering wheel, above the driver's feet. Here are the connections;
Again, it's only necessary to connect to the OBD port for Engine / Transmission diagnostics. You'll also need your computer to connect to the Kracker;
Hardware setup is all done. Now on to your software choices;
NavCoder is designed mostly for setting / reading accessory options (Radio, A/C, Lights) — you'll use it while connected to the trunk. It's not as powerful as other programs, but it's very easy to use, especially for setting Radio/Nav options and other customizations.
INPA is my favorite, it's an internal program used by BMW to do vehicle production testing, and has a simple, fast interface. INPA also includes NCSexpert, which we'll use to set car customizations later on.
To set up INPA, begin by downloading it (600MB) and unpacking the zip to a new folder. Start setup by double clicking on Programminstallation\setup.exe.
If you're using Windows 7, before you run setup.exe, select Properties >> Compatibility and set 'Run this program in compatibility mode' >> 'Windows XP SP 3';
You want to set the hardware interface to STD:OBD, the only other setup question you need to pay attention to is the port settings;
Select the Car Kracker's Com port, and check ''USB-to-serial adapter'. Once the setup completes, reboot your computer.
After your computer reboots, run \Referenz.2005\INSTALL\Instprog.exe. This will update your installation with the necessary scripts for your car. NOTE: Instprog.exe can't be within a folder that has a space in its name. c:\users\John Doe\INPA won't work. Copy the referenz.2005 directory to a folder without spaces, like c:\users\docs\INPA.
On the first screen, just click 'OK', and select English as the install language.
Select BMW Group Recertification Programs UK and click OK;
Finally, select Update / Complete on each item;
All done! Plug your Car Kracker into your car and open INPA(_.IPO). default install; C:\EC-APPS\INPA\BIN\INPALOAD.exe. Your ignition has to be on to read Transmission / Engine data.
The Car Kracker 3 emulates a CD changer, and can play audio files stored on a µSD card, or enable Aux-in. There's also an optional connection for DSP support. Here are some tips on using music mode.
In the Kustomizer, set the default boot mode to 'Music Player';
In the Music tab, you can remap the CD change buttons on the radio to do other things;
I usually remap CD1 and CD2 to switch between CD's. This also lets you have more than six albums. If you only want to use the Kracker for Aux-in, set the default audio source to 'Just open Aux-in'. If you have a DSP, set the default audio output to 'DSP'. With analog audio, I suggest setting the volume to '2'.
Using Bluetooth Audio
Here's a video walkthrough on setting up Bluetooth Audio;
Any Bluetooth Audio adapter should work, I've been using this one, but there are many choices. In the Kustomizer, set your audio source to 'Just open Aux-in'.
The Car Kracker 3 also offers 5V power to keep the Audio Adapter powered up. All the adapters I've found use 5V to charge — look for one that comes with a USB 'charging cable'.
Playing audio from the SD card
You can also play audio files directly from any microSD / SDHC card. 44kHz and 48kHz wav files are supported, which is CD quality, although MP3, AAC, and WMA files will need to be converted. Audacity is my preferred program for conversion and it's free. Here's how to convert files;
You can use the buttons on your radio to move between albums and tracks, be sure to map them in the Kustomizer. Albums are grouped by filename, your SD card should look something like this;
01-01.wav 01-02.wav 01-03.wav 02-01.wav 02-02.wav and so on...
Put everything on the root of the card, no need to use directories. Most radios support 99 tracks per album. My radio supports several dozen albums, although the display doesn't count past 9.
