2019 mdx has had infotainment failures since day 3. Intermittent failure of both screens even when phone not connected or in car. Acura couldn’t diagnose nor fix, told me it was a problem with my iPhone, tried their tech services and customer relations but they did nothing.I wanted to replace a new one, but they said the price was too high and I had to give it up, which made me very frustrated. i finally found Ai Box wireless carPlay adapter dongle - convert my carplay to Android system.In this way I not only upgraded the wireless carplay but also have an Android system.It has worked great for me every time. Haven't had an issue so far. Never thought I would like that feature so much, but it is one of my favorites.
