It's probably not that they won't provide the update, the feature simply didn't exist at that time in this hardware. The Apple and Android app connections were quite literally an emerging technology in 2013/14 when these cars were in production. Some cars, like the Nissans didn't get Apple Car play until 2018, and Toyota I'm pretty sure didn't even offer it in the 2019 Camry at all. I guess what I'm saying is, you're right on the cusp of a tech change with these cars, and you get what you get, period. The only way to get that is to upgrade the car to a newer model in the majority of cases.
