The connectors used are prepared for direct connection to the CIC computer and the corresponding sections of the main harness, without the need for modifications to the installation.

This solution allows for maintaining:

• consistency with original brackets and cable routing,
• correct harness positioning relative to interior components,
• easier service access during subsequent diagnostic work.

Benefits of Using an Original BMW Cable

Using a cable designed for the CIC system in BMW E60 and E90 LCI is crucial for the stable operation of the entire multimedia system. Compared to universal or adapted solutions, the original component ensures:

• reliable compatibility with BMW's electrical architecture,
• proper cooperation with the CIC computer and other comfort modules,
• reduced risk of signal interference and communication errors in the vehicle's bus system.

For workshops specializing in the BMW brand and users upgrading their multimedia systems, this is a solution that facilitates the maintenance of factory installation and diagnostic standards.
