ACV Steering wheel control interface

This car radio connection provides an interface between the Mercedes vehicle networks and HER retrofit audio devices. It translates steering wheel buttons into commands that are understood by new car radios and uses the vehicle's CAN bus, where necessary, to ensure communication integrity. The installation consists of connecting the adapter to the original radio harness and the wiring of the retrofit car radio. Thus, the original remote control functions and the OEM navigation interfaces can still be used. Typical uses include replacing the factory audio 20 or audio 50 systems with a 2-DIN retrofit device, with Harman Kardon sound systems and NTG2/NTG2.5-COMAND functions still working. The adapter is designed for direct integration into the original plug configurations of different Mercedes models, WAS simplifies installation and reduces cable splicing.
