It’s a shame that Toyota didn’t set up the mirror link or whatever without a certain amount of flexibility viz a viz futureproofness. They should know people change mobile phones more often than they change cars so to have a system relying on an iPhone 4S, which came out 3 years before the car did, was flawed at best and negligent at worst. So even the person who bought my 65 plate (UK) new quite possibly had an iPhone 6s when they bought the car and could never use the mirror link.
