Hi there I have a questions . My factory sound system powers on and everything seems to be working except there is no sound, sometimes it comes on, everything works just fine radio, navi and tape . whenever there is no sound it won't recognize cd changer, ( it says NO CD CHANGER ) . Does
anyone had this before ????

 

You don't state vehicle/radio type / history / age etc.

Does your installation have a remote CD changer in the boot?

If so it is possible that the D2B fibre highway (connects audio systems together e.g. telephone module) is breached at some point due to a bad connector.

If you have a CD changer I would start at this point.
I have no specific experience on such a fault other than if it works sometimes and not others it shouldn't be to difficult to locate the problem.

SO?

I've suggested what might be wrong. You need to determine whether my diagnosis is correct.
