The Connects2 CTSMC014.2 steering wheel control interface allows you to retain factory steering wheel audio controls when upgrading to an aftermarket head unit in select Smart vehicles. It preserves OEM button functions so audio control remains integrated with the new stereo.

The unit offers plug-and-play installation with no cutting or soldering required and connects to the factory wiring harness. It supports major aftermarket brands including Alpine, Sony, Kenwood, and Pioneer; a patch lead may be required for some head units. Vehicle specific fitment applies.
