I´ve bought an aftermarket indash double din dvdplayer/gps built in, with bluetooth and rearview camera, it all works , but the steering wheel controls are not working, when i turn on the ignition it makes an unstopable sound, when i connect the steering wheel wire from the radio to the white/violet wire of the car , I run the menu to the steering wheel controls configurition and than it stops. but still no controls , can you help me ?I´ve talked with the seller and he told me that the radio receives resistance signal on the steering wheel wire but what wire of the car do I connect to this one? My car is an Chrysler Voyager LX 2500cc 12/2004 Daimler/Chrysler.
