I Have a 2016 Prius and every time I turn the car off I have to reset my bluetooth (turn by off/on) because otherwise the audio goes in and out continuousl, it started out doing it very spartically then in the past month and half was doing it everything I restarted the car, then about a week ago once I connected my phone it would not automatically recognize my music. I would have to open iTunes on the phone and select my music before it would play, but it wouldn't not display the what was playing on the car display. Today toyota changed out my radio, seems to connect properly now, but messaging is still a 20/80 success/ fails. Email has never worked. Toyota tech's connected their android and works like a charm. One tech with an iPhone as well said it's a hit miss with his and that it has to do with Apple and the way they it releases mac address, etc. The same type issue that we have experienced Apple products in an enterprise enviornment, which can make it hard for our users to pass security policies, firewalls, etc... Apple products are NOT enterprise friendly which really them more of a consumer product than a business use device. They have gotten better, but still quirky. Also the comment about cars using old BT technology/protocol, is really like saying it's Microsoft fault that Apple has problems with Outlook, never mind the fact that every other computer manufacturer doesn't have the issues that mac's seem to suffer. Here's a novel idea, why doesn't Apple make their devices play well with others. Make their BT backwards compatible for one example and stop acting like a narcissistic spoiled brat child. Do get me wrong, they make some great stuff and I own several of their products as well as others. In my field I see and deal with a lot of systems and issues and work with support with all of them and what I have found is all of their poop stinks, when they poop, but Apple is the worst at admitting it. Android works great with my car, so I know Apple can make it work great as well, but they won't..... peace, love, hugs and kisses
