Hi, I have question about bluetooth. I have a car ( lexus is 250 ) with build on hands free system. (mark levinson)
Unfortunatly my phone Oneplus 3 doesnt connects with car bluetooth. I have last firmware on phone ( android 7.0 oxygen 4.0.3 )
Oneplus 3 have Bluetooth® 4.2.
I tryed to connect iphone 7, Galaxy s7 with car and it's works good ! Iphone 7 have same bluetooth version 4.2
When I'm trying to connect, I see this message on car display: Bluetooth connection failed. Please check, the Pass key and he setting of the phone

Other devices works good with oneplus 3 bluetooth

 

There's a max limit of devices that can be registered to the BT in the car, try deleting one of the ones you don't use and try again?

 

Hi, It isn't problem with limit of devices.
It's problem with oneplus three software compability.
Now I'm working with oneplus support, hope they would help me
