[Rick01]

Hi everyone looking for some help, I've got a 1998 CLK 320 sport with TV screens in the headrests but have no idea how to work them I cant even switch them on, Its not dvd as there is no where to put a dvd in can anyone help

Thanks in advance

Could be the equipment is in the boot/under the rear seat and controlled by a remote control or by the front head unit. Or the previous owner took the bulk of it leaving only the head rests. Post up the manufacturer of the screens if possible-might help identify the system.

The screens are sony the cd changer is in the boot no dvd or anything like that, the head unit is just the radio and heater. its got me lost
