    Recently bought a 2013 International 8600. Quite the upgrade from our 1986 International 9370 Eagle! There is one switch on the console that I’m not familiar with. It’s labeled “MRK INTR.”
    Can’t seem to find it in my owners manual. Can anyone tell me what this switch is for?

    "MRK INTR" is now on the Steering Wheel marked as MARKER INT. Very handy with that one on the right easily assesable with just a thumb movement and the HEADLIGHT INT on the opposite right side of the wheel. I absolutely love my 2015 Prostar despite what others say. I've actually fixed every glitch I've come across including the "Antenna Ground Issue" that's not at all a ground issue but a "too many wires and an AM/FM/CB SPLITTER ISSUE" instead. Gotta love the Cummins ISX too.
