QuadLock

Main connector behind infotainment unit. Originally it featured 4 blocks of pins - hence the name. Since the original 1st generation of QuadLock, infotainment needs changed and the connector evolved. Basic shape stayed the same but block structure was adapted for newer system requirements.
