Aerpro CT10MC05 T-Harness for Mercedes
T-harnesses let you integrate an additional device such as an aftermarket Bluetooth kit into your car's factory radio and its wiring.
This allows your aftermarket Bluetooth kit to work with your car's speakers directly when on a phone call and revert back to the stereo when the phone is not in use.
