I have a 2018 Highlander and my cell phone disconnects from the Entune system (Bluetooth) while in use. My wife phone disconnects also. I’ve brought it back to the dealership several times and they can’t fix it. They gave me some instructions so I could resolve this issue and basically said I’m on my own. I also just purchased a 2021 Corolla and my iPhone works just fine in it so I don’t believe it’s a problem with our iPhones. I’m really disappointed with the service I’m receiving and I also purchased the Extended coverage which now seems like a waist of money.
