It's been a while since I've been around here, but I have a problem that I'm trying to find a solution to.

I have an MP3 player for my TC, but it's a bit older now and the battery is dieing. So to solve this, I bought a car charger for it. But now there's an issue. When it's on, and the charger is plugged in, there's a buzzing/squealing sound coming from the speakers. It gets louder and softer based on the RPMs too. When I disconnect the charger, the sound goes away...but so does the music since the battery craps out on me.

I have the charger plugged into the AC outlet that's next to the audio in port.

This is the charger: http://www.amazon.com/gp/product/B000JTA42Q

Is there any way for me to shield the MP3 player/charger from this interference?

 

It's all about the ground.

Haven't really taken the time to isolate it but I'm pretty sure it's been discussed on here often with the iPod connectivity.

 

So is there anything I can do about it or do I have to live with it?

 

I know people have fixed it with the iPod, but I really can't remember how.

Possibly try moving the HU ground to something better than the stock one.

 

If I had any idea how to do that, I would.

Is there any kind of write up or FAQ on here for that?

 

So I pulled apart the stereo today to try and find the HU ground, or even just the AUX ground...

...and I have no idea where it is on this.

I have an 07 TC with a Pioneer T1806.

Can anyone help?

 

mandos thank you so much for saying that. I stated this in another thread and people thought it was a joke.
Try and find the AUX ground and ground it to the same spot as the radio. I dont have stock stuff so I cant help you out sorry. But I will look around.

 

Well I took pictures of the wiring to see if anyone could help me identify the ground, but they came out all blurry. I'll have to try again another time.
