Good news for both of you: I rented a 2022 Corolla and it supported both CarPlay and Android Auto. Toyota gave in!

Well they got about 4 years before I need another car, unfortunately for them my new minimum requirements are going to also include EV. VW id.4 is my current leader.

Might be worth swapping out the head unit. Best Buy will sell you a Sony unit with installation for $250 for example.

I've thought about that. I'd want one that supports the backup camera and all that. Do you know offhand if those exist at reasonable prices?

The last time I replaced a unit was in 2012, but I think what you would be looking for is a head unit that accepts camera input , a wiring harness for the head unit to the car's wiring, a reverse camera adapter if the car doesn't use the standard yellow RCA-esque connector (apparently toyota uses several different connectors), and a interface adapter if you want to retain the use of the steering wheel controls which in total would probably be <$500 depending on parts. I remember Crutchfield's "will it fit" tools and advisors being pretty helpful.

Looking around a bit, apparently there's also a neat though slightly more expensive product called the datalink maestro rr or rr2 that does the camera and head unit interfacing part while retaining additional features.

Toyota themselves have started offering upgrades of older models to support CarPlay or Android Auto. Costs about $200.
