The main advantages of this solution include:

• preserving the original operating ergonomics,
• consistency with safety and comfort systems,
• reducing the risk of communication issues within the vehicle's electrical network.

In practice, this means it is necessary to check:

• compatibility of the body type and model generation,
• configuration of comfort and safety systems,
• type of steering column used.
