I recently changed my radio everything works fine exept the speakers. I am 100% sure that i hooked up everything right its just that the spearker controller is burnt (thats what my mechanic said) he told me to buy it onling and replace it and he mentioned that the name of the controller or the chip is called magio. Does anyone have any idea how to find one? I have a g35 2007 coupe manual.

 

Do you have the Bose system?
