Bluetooth always loses trust
For months I've been trying to fix this really annoying issue. I have even downgraded from 5416 firmware but still every time I get in the vehicle I have to re trust my Bluetooth with the pin code. Please help
Hi
First, please check if there is a Bluetooth module under your passenger seat and driver's seat. If there is, please unplug the module. Let it stop working completely.
You test like this.
1. You connect your mobile phone and the unit's Bluetooth, after the connection is successful. You do not turn off the car, and then restart your mobile phone to check whether it can automatically connect with the car. If you still need to re-enter the PIN, it means that the problem is on the phone, because at this time your Bluetooth information has been saved in the car.
2. Change to another mobile phone with a different operating system, such as an Android system and an IOS system, and test separately to see if the problems exist. If the same problem occurs, you need to check the Bluetooth module of the unit.
3. Enter the developer mode of the unit and check whether the relevant information of the Bluetooth module is abnormal.
