unable to auto connect bluetooth

I have to reconnect my phone to the vehicle's bluetooth every time I start the vehicle.

When I turn off the ignition of the vehicle, the connection goes away and when I restart the vehicle, it does not connect automatically.

I have to re-pair, enter pins and do the operations.

I tried with different phones, the result is always the same.

similar problem There are people who are living with me and they couldn't find a solution.

I went to the Peugeot service. He dismissed the issue by saying that all peugeot vehicles are the same, etc. In order not to prolong the polemic and not get nervous any more, I said tmm and left immediately.

Is there a solution to this?
