I just ordered a switching box for my new CX-9. $110...holy crap (never mind that the full retail price is over $140). I don't even want to know what installation will cost, might attempt to do it myself.
 
Next step will likely be to order a ground loop insulator once I power up the iPod (my iPod battery doesn't last too long these days, so I have to plug it in).
 
It's ridiculous that I have to take all these steps to listen to a MP3 player. This might explain the terrible rating for Audio in Consumer Reports. Oh well...at least activating the Sirius was painless! And I do enjoy driving the CX-9! It's awesome!

Do you know what brands incorporate a ground loop isolator in their aux jacks?
 
From what I have read, this should be taken care of on the power input side rather than the sound out side.
 
I've heard that wrapping the power cord around a ferrite core will eliminate the noise. So, maybe you should ask Microsoft why the Zune comes with an unfiltered power supply.

I think poking fingers at Microsoft for the Zune is silly when many others have complained that other devices (including iPods) plugged into power and AUX cause the same problem.
 
As to what models do filter it - all I can say is that my Mini Cooper didn't have this problem.

This is a known issue in the CX-9. You need a ground loop insulator, available here. That will solve the issue.
Not sure why a ground loop insulator is not built-in...

 
nxs138, thanks for supplying that link to the ground loop insulator. I was planning to take my car to the dealer to have this checked, but for $20, I may just buy this device and be done with it. Wasting my time at the dealership while they try to figure out what's wrong (when they may end up charging me anyway) might not be the best way to go.
 
I wasted 2 hours there last time, to have them change the locks to rolling/auto locks.....only to have them tell me it couldn't be done....which I'm not convinced is true.
 
Anyway - thanks for all the feedback!

After reading all previous posts, here is my understanding of the iPod issue in review. If anyone finds any flaws in my logic, let me know, as I am dealing with the same issue right now.
 
The back of the radio has one input, which comes connected to the Aux port in the center console by default from the factory as long as you didn't purchase any add-ons (Sirus or iPod Integration Module). No problems so far. Now let say you would like one of the previously listed add-ons. These add-ons need to be connected to the same single plug in on the back of the radio. It sounds like a lot of the submitted issues come from the dealers simply disconnecting the Aux and connecting the add-on, rendering the Aux useless. Along comes the Switch Box. This device sounds like it plugs into the back of the radio, then Ys, allowing two devices to be plugged in, such as the original Aux and one add-on. Since there are three devices currently available (Sirus, Aux, iPod Integration Module), the Switch Box allows two of the three to be connected. Without the Switch Box, the user can just pick which item they want connected but nothing else will work. Ok, manifesto complete.

Just to be clear, the Switching Box only works with AUX and another accessory. You cannot connect Sirius and iPod at the same time.

Ok, good to know. So in my situation, I would like the iPod Integration Module (IIP) to work with my radio/NAV system. If I have them install the Switching Box, my Aux should continue to work, where without it, only the IIP would work. Are there any other factors in making this choice? My dealer says he tried once before without luck but I don't know which method they used. Any further help is appreciated.

I am having the same problem as epicard. When test driving I took along a Jukebox cd with mp3 songs on it to test the system. Most salespeople seem to think that the AUX plugin for an Ipod is "THE MP3" player. My car was the "touring" model with the Bose/sunroof package. I finally got around to making some new mp3 discs only to find out that, while recognized by the system, there was no sound. Now, to make things more interesting, I received from Mazda, a package thanking me for my purchase of a new CX-9.
 
One of the preprinted pamphlets (#9999-92-cust-cxp-08) "getting to know your CX-9" reviews features on the car. In the audio system section it states, and I quote.
 
"Bose Centerpoint surround sound expands the two-channel stereo mix of conventional CD's, MP3-encoded CD's and (when played from the rear seat entertainment system) DVD's encoded in two-channel stereo into five channels."
 
Obviously there is a major screwup here on Mazdas' part. I have called Mazdas customer service at 1-800-222-5500 and spoken to "Austin" who never gets back to me with an answer. As far as I am concerned, I was sold an audio unit capable of playing MP3 encoded CD's and I will settle for no less than that. Especially as their own owner info confirms the ability of Bose system as an mp3 encoded cd player.
 
Love some feedback on this. Roger

As an update, I got my hands on the installation instructions for both Sirus and the iPod Integration Module. In the end, both have a 16-pin connector that fits the back of the stereo. So, you can have one or the other, but regardless of what you pick, the addition of the Switching Box allows the retained use of the Aux. All right on with what you said Maltb. So, in closing, does anyone have the iPod Integration Module, and more importantly, does anyone have it installed with the NAV system? There has got to be someone out there...
