I'm facing a problem with Bluetooth and the car a few minutes ago logged in normally and now the car's multimedia error is coming out .... I connect another phone I work normally I have the XZ2 compact

I made the change in avrcp setting 1.4 1.5 1.6 but the problem is the same

@kostasf1

Did you try unpairing the phone, removing the phone from the car's paired list and the car from phones list? 

[kostasf1]

The car does not have a list

[kostasf1]
