Sounds like a potential business opportunity! I don't know much about cars, how much is standardized in car electronics? Would it be possible to build a infotainment module that you could sell to several car manufacturers with only minimal modifications?

I think I've heard of something called an ICANN(?) bus that is used to communicate stuff in cars and is fairly standardised, maybe?

It's CAN, and it's old serial technology.

There are already companies doing 3rd party electronics as mentioned above, such as Visteon and Continental, and Garmin is trying to get into that business too.

That's what many OEMs have been doing for decades and this is exactly what many SDV have been trying to get rid of, since integrating many different products from many different manufacturers are slow, let alone iterating and designing new features.

Related to CAN, the bus is standard, but the thing is, CAN is just a bus, not a protocol. There are many ways you can have two ECUs (vehicle's modules) talking in incompatible ways.

ITYM "CAN bus" - https://en.wikipedia.org/wiki/CAN_bus

Pioneer has been selling standard-sized Android Auto head units for over a decade at this point.
