Pioneer AVH-X8800BT
Thank you very much for your help in solving the problem with the blocked car radio by password.
(sorry for a machine translation, but I wanted to share my experience)
In 2016 I bought (for about $ 1000) the smart car radio AVH-X8800BT and secured it with a password. Everything worked to complete satisfaction. Sometimes it was necessary to unblock the car radio with a password after unplugging the car battery - all without a problem. In the meantime, I updated the firmware (downloaded from the manufacturer's website) to version 1.05 - everything worked
