The CarAV 16-058 is a vehicle-specific adapter harness designed to connect aftermarket head units to the factory wiring in Volkswagen Touareg vehicles. It provides a direct interface between the vehicle connector and standard aftermarket radio connectors.

The harness preserves factory plugs for reversible installation and reduces installation time by avoiding wire cutting. It is suited for installers fitting aftermarket radios where a compatible vehicle wiring adaptor is required.
