I wouldn't go looking for answer on the ROI just be happy it doesn't work mine doesn't on my x728 and I'm not looking for answers. Just buy a nice set of radio headphones and enjoy the ride
455's didn't have a RIO until 1998 or so.The PTO does NOT automatically turn off when I put the machine in reverse.
I do not know if this is a malfunction or if this is the way it is supposed to work.
