Volkswagen have RCD head units that are compatible between VW and Škoda cars. RCD/RNS 210, 300, 310, 320, 330, 360, 510, 560, etc are all interchangeable and some are touchscreen-based, others are button-based. I think they also do the same for SEAT and Cupra cars, though head units have different models. I'm not so sure compatibility with the car is the reason. Maybe it's more about maintaining one branch of software for more head units.
