I was one of the early 12iS builders with full interior and I had to send Abby photos and dimensions so she could incorporate a cutout around the vent flap. I would have thought she would have incorporate that modification as standard. Same with the cutout around the headphone jacks - not enough clearance for LEMO and aux output plugs. Maybe it's the one for the ULS instead of the iS? Sorry, no photos of mine.
