Peugeot407sw Bj2005 JBL Soundsystem

[Stefan]

Hello, I have a 2005 Peugeot 407 SW with a JBL sound system. I bought an Android radio to replace the built-in one and installed it. Everything works fine except for the sound. About every two minutes, the sound cuts out for approximately 20 seconds. The volume control on the steering wheel is also malfunctioning. If I want to lower the volume by one notch, I have to turn it down two notches before the radio goes silent. Only when I turn it up one notch do I get sound again. I have the attached adapter, but I'm unsure if it's compatible with the JBL sound system. Can you help me?
