Aux input has unwanted noise

I've barely had my TSX for two months, and already I have two minor but annoying problems. One is the squeaky windows, on which there is already a thread. The other is that when the stereo is set to the aux input, the stereo emits a loud static-type noise.

Into the aux jack I've plugged an ipod (an old, second generation model). The ipod is also plugged into the power jack in the center console. The ipod's wired remote is hanging just in front of the center console.

What makes this even more interesting is that the noise seems to vary in pitch with the RPM. The higher the RPM, the higher the pitch. It is about the same volume, though.

Neither affect the driveability of the car; however both (that is, the windows and the stereo) are things I's like to frequently use. If anyone has any idea how to fix this, I'm very interested.

It sounds like you may have excessive "ground" noise on your aux input. You can install a ground loop isolator (buy at any car stereo shop) that should take care of it. You might be able to get Acura to check it out for you as I doubt this is "normal".

You might wanna double check that your cable is plugged in fully to the Aux jack. Think there was a thread from a new 06 owner regarding similar issues.

Is the cable that you are using to run the audio signal to the aux input plug wrapped around the power chord or even run along side of it? That might be the problem. Kinda along the same lines as not running your RCA cables and your power wire next to each other. Try using it without the power chord plugged in and see if you get the noise.

I notice that too - but it's faint in the back ground....it's noticeable only when the ipod is plugged into the power outlet...so I usually keep the ipod power plugged, but disconnect the power when I am listening to the music.

Yeah, try what CJams suggested. If that doesn't work, make the dealer try to take care of it.

If that doesn't work you have a couple of options. You can put an inline noise filter on the positive input going into the cigarette lighter. If you can get some of the quick disconnect connectors, you won't have to splice the wire, just hook it up in series to the existing plug on the 12v power outlet. If you remove the rubber mat then there is a screw on the bottom of the center armrest bin. Remove that and you should be able to get to the wiring without having to take off the transmission area cover.

If that doesn't work you can get one of the ground loop isolators that have the RCA plugs. This is a kinda messy solution because you'll have to go from 1.8 mm headphone jack to RCA, then back to 1.8 mm jack to plug it into the AUX input. And you'll have all of these wires in the center armrest.

Good luck!

Thank you all for the ideas. The noise does indeed go away when I unplug the ipod. Which leads me to declare this, locating the two plugs in very close proximity, a design flaw. Because this ipod is old and crappy, the battery doesn't last much more than 20 minutes, which is why it ended up as a car stereo in the first place. I think I'll give the dealer a call tomorrow, I'll give the inline filter a try.

you need a ground loop isolator, they are dirt cheap.

Just found a GLI with 3.5 mm inputs/outputs made by PAC. I didn't know they existed before. If you have this, you can just connect it directly from your ipod to the AUX input along with your current 3.5mm cable. Pac usually makes good stuff and this is probably the most simple and easiest solution.

I have a similar, but different problem. My TSX is about 1 month old.
I have a fifth gen video ipod that I play through the auxillary jack.
I run the ipod off it's own battery. With certain songs, I get alot of static, but with others I get very little if any static.
No static with XM, CD, or FM reception

Anyone know what could be causing this. I've made sure I have the jack at both ends plugged in fully.

Thanks

Peart....are you using dock to stereo connector or just stereo to stereo? Try get the Dock to Stereo connector, they are much better and will not get any static because it is not through your headphone jack.

the 12V power plug is not working well. Get another 12V power plug.

I ordered the GLI today from Crutchfield. Even if a new 12v outlet is covered under warranty, I'd as soon avoid taking the car in. And if it isn't covered, it seems easier to try the GLI before installing a new outlet. I'll post the results when it arrives.

Just went to radio shack today planning to pick up a GLI, and the person told me that it's not going to fix the problem. I told him my situation....which is humming noise when my ipod is plugged in and i can only hear it when there's no music on. I have an iPod mini and i'm using a belkin auto kit.
