I have a problem with the CD Changer recently. My CD Changer would start up fine once I start the car, but after I drive for a while, the CD changer would keep working but the sound from the speaker would fade out. As if someone has turn off the volume. The AM/FM radio works fine, the problem is only with the CD Changer. I got a 05 Mazda6 V6 MXT and I love driving it. Fellow members, please help.
