> Also, interesting how they didn't think to design their own entertainment system because... cars had third party entertainment systems that's just the way it was!

This was rarely true in 1999, at least in the US.

They often had ones that were standard DIN or double-DIN size, but they were usually manufacturer-branded and styled with buttons that matched the rest of the car.

But if you google image search a 1999 Ford Taurus interior you'll see that not everyone was even then still sticking to the easily-swappable standard. Compare to 1999 Camry, which had standard size but came out of the factory with a Toyota-skinned radio of one sort or another depending on options.
