Infotainment steering wheel adapter. Settings on the on-board computer, air-conditioning control display, PDC (Park Distance Control) and much more are displayed on the monitor of the aftermarket device. In order to be able to display information from the on-board computer, the new device must have a colour monitor and a rear-view camera input. Switching to vehicle-specific information is achieved via "reverse" from the infotainment adapter to the reversing camera input from the device.
