I gave up, too many trips to the dealership for this, then rejected further exploration on my Shaker since they found I had installed Polk Audio 5x7's in the factory locations and NO other mods. Sad how Ford thinks the distortion is normal to the Shaker 500 in the Mustang. We also have a 2012 Explorer with the Sony Nav Audio system, and it has great a audio system with NO noise. I recently traded the Mustang for a different needing 4 doors (fear not- NO Chevy/NO Dodge sought) and ended up with a VW GTI. I would have jumped in a Focus ST, but feared the same service woes I did with the Mustang. (sorry guys). The Explorer is keeper though...

The root cause is internal to the radio head. Either line filters are not there, are cheap ones, or circuit design flaw. Swaping parts just won't fix this. The radio head needs to have its design fixed and new ones made. With today's electronics it is too hard to jus swap internal parts. Making new head units would cost Ford too much. I would guess they would fis this in the next radio design, but that is probably the 2014.5. We just have to live with it. At least that is what I came to after trying to get it addressed a while back. Just turn up the radio or put on louder mufflers :-)

Why has this gone cold as of 2012???!!!!
Is there a different forum on this?
Can someone chime in because I cant fathom how this can be considered acceptable in a $70000 car.
A $10000 Saturn doesnt do this???!!!!!!

I think Ford's "give a damn" ran out on this issue a long time ago. Mine has done it since the day I bought it off the lot. They replaced the head unit and the amplifier... Still does it. Dealership stated it was "acceptable."

I think people that are that picky about their audio should use aftermarket equipment. Some people have some high expectations for a factory stereo system. I think it's better than most any factory system I've heard. If the issue really is the head unit replacing that would seem like a no-brainer, get a new good quality one.

For the record, didn't have any issues with my 07 shaker 500 or my current 2012 shaker 500... everything works great.

edit: read how people are achieving this, engine off in a quiet location with no music and the volume turned on? WOW!! how picky do you have to be to find this? there is an off-button on it. if you aren't listening to it, turn it off. Like i said, if i were this picky I'd just go aftermarket and get good quality stuff.


btw...I have a $5,000 home audio setup that also "has white noise" under these conditions.. LOL! It's because it's sending what signal it is getting to the speakers. (with no audio present that means any electrical noise there is)

To everyone in this thread: It's working as intended.
