ACN offers the Handsfree System in both a customized and universal fashion. Customized kits include factory look-alike switches designed to fit directly into the knock-out plugs currently on your vehicle's dashboard. They allow you to retain your automobile's factory finish, all while adding the benefits of a handsfree, voice-activated calling system. Customized kits also include wiring harnesses designed to tie directly into the wiring already on the vehicle.
