iDrive tools for packing and unpacking BMW backups

Tools for managing BMW iDrive music backups. There are two tools included in this package.

bmwunpack

This takes a BMW backup and converts everything to regular media files.

Typical arguments contain the source and destination folders.

Usage

bmwunpack BMWData unpacked

bmwpack

This is the opposite of bmwunpack in that it will take a hierarchy of folders and create a BMW backup that can be restored back into the iDrive system

Usage

bmwpack unpacked BMWData

Notes

A typical BMW backup has a single BMWData top folder, a Music sub-folder, USB drive name sub-folders below that and then the actual media files themselves.

There are several metadata files that are required by the backup. These files are calculated by bmwpack and added automatically. Without these metadata files, the backup will not be recognised by the iDrive system.

An example backup file structure.

BMWData
+ Music
  + USB1
    + Media folder 1
      + file1.mp3
      + file2.mp3
      + file3.mp3

There are several file types that are supported by this script. I suspect there are more file types that are supported by the iDrive system. These are the ones I have come across so far and their “encrypted” extensions:

Media files

• MP3 (BR4, BR28)

• MP4 (BR3, BR27)

• AAC (BR25)

• FLAC (BR48)

• WMA (BR5, BR29)

• JPG (BR67)

• BMWP (BR30) - A playlist file

Playlist Support

The BMWP playlist file is a plain text file that contains a list of absolute paths located on the iDrive system itself. They start from the USB drive name going forwards with a UNIX file format name (forward slashes). They typically look like this:

/USB1/CAKE - Pressure Chief/01 - CAKE - Wheels.mp3
/USB1/CAKE - Pressure Chief/02 - CAKE - No Phone.mp3
/USB1/CAKE - Pressure Chief/03 - CAKE - Take It All Away.mp3
/USB1/CAKE - Pressure Chief/04 - CAKE - Dime.mp3
/USB1/CAKE - Pressure Chief/05 - CAKE - Carbon Monoxide.mp3
/USB1/CAKE - Pressure Chief/06 - CAKE - The Guitar Man.mp3
/USB1/CAKE - Pressure Chief/07 - CAKE - Waiting.mp3
/USB1/CAKE - Pressure Chief/08 - CAKE - Baskets.mp3
/USB1/CAKE - Pressure Chief/09 - CAKE - End of the Movie.mp3
/USB1/CAKE - Pressure Chief/10 - CAKE - Palm of Your Hand.mp3
/USB1/CAKE - Pressure Chief/11 - CAKE - Tougher Than It Is.mp3

These can be edited to keep the same absolute path. They are included in the _Playlists folder.
