So you work for Toyota and place all the blame on Apple? Toyota has many in arbitration for this failure. When I purchased a new car, I expect new technology, in fact it was the reason I purchased a new car. My dealership ended up being the one to make things right for me. NOT Toyota. They know it’s their cheap outdated system they put in 2019 and are depending on Apple to bring it up to Standards. If not being able to sync your contacts, or use the Entune system as advertised is no problems works fine, your quality of good work is unacceptable after paying the price for a new Toyota vehicle. Half a fix, is probably all the other older Toyota owners will get. The the 4 runners, I have no knowledge of, but if the Entune system doesn’t work as advertised, it’s not fixed.
