Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Hard Disk Drive
With the development CIC, a hard disk for storing applications (programs) and data is used in a head unit of a BMW vehicle for the first time.
A 2.5" hard disk drive with a storage a capacity of 80 GB is installed.
This makes it possible to display complex graphics like 3D models in the perspective view of the navigation system.
This system provides the option of converting, storing and playing music tracks.
The hard disk makes it possible to maintain a music collection with a music track database (Gracenote®).
The HDD (hard disk drive) also provides a data storage option for the three languages of the voice recognition system.
The hard disk drive is a replaceable component of the CIC. Proper repair instructions and ESD guidelines must be followed when replacing the unit.
The Music collection backup should only be performed by the customer and not the service technician. For more information refer to "MUSIC COLLECTION BACKUP " in the Principles of Operation section of this training material.
The following illustrations show the hard disk location and the individual partitions.
