Older example but when I got a second hand Mazda in ~2017, the salesperson I bought it from set up Bluetooth pairing for voice calls via my phone.
As it turned out, the feature was still pretty janky and I only tried it a few times before reverting to just regular speakerphone. And when the battery died and the head unit lost all its config, I never bothered figuring out how to set it up a second time.
