That's because in car GPS tech has historically been absolutely atrocious. An example: 2008-2012ish Toyota Camrys had a GPS system that used a DVD for map data.

That's because in car GPS tech has historically been absolutely atrocious. An example: 2008-2012ish Toyota Camrys had a GPS system that used a DVD for map data. Not only was it out of date immediately (and cost $150 per new DVD from the dealer), it was insanely slow. Nowadays, there's a few companies that actually seem to do a decent job of GPS in the car itself: Mercedes has a good tech in their new EVs that seems smooth. Android automotive (not auto) cars have built in Google maps such as Polestar, the new Cadillac EVs, and some other Chevy products do well. Although it's not much different than just having an android phone with android auto. And, of course, Teslas own system which is all inhouse. There's little reason to use a phone in the traditional phone holders if you own one of those cars.
