Noise Transfered to Droid by VZW Car Charger

[Trek6500mt]

I have posted in a few other are'a but haven't received but a couple of returns. So I have the Motorola Droid, "Love It!" I'm using it to send streaming audio from Pandora through a 3.5mm male to male cable to my XM receivers Aux input port, then transmit it via FM xmiter to my car stereo. Now you would think with all these possibliies for noise in all the connections and such it wouldnt be the VZW car charger. But as soon as you unplug the phone from the charger the noise stops and it sounds beautiful. Now one forum member said he had the same problem and read that Bluetooh was the only way to stop the noise. Could this be true? This would make my Droid to me usless until I purchased a new Bluetooth A2DP compatible stereo for the truck. Shouldn't have to do that. So does anyone know of a car charger for the Droid that is insulated or have used one in the same way I'm using mine without the noise problem? I would be very greatful for any info.

Thanks in advance.!!

Well its the trucks cigarette lighter. I wonder if there is a hard wired charger that could be installed? I called crutchfield asking if they knew of any type of filter I could install, but they said they only have filters for speakers. Maybe I need to replace the whole lighter...

I would look for a loose connection and check your battery cables....

Put a filter in the power line and that will go away..

Thanks for the web page.
I read this article wondering if it was what you intended for me to.
"How to dynamically mitigate power supply noise." Its a little over my head though. :unsure: But I will check my battery connections after work tonight.

I get a high pitched noise during acceleration and a crackling static like noise all the time while I'm charging the phone and using for music at the same time. When I unplug it and just use the aux port it is crystal clear for the most part.

Maybe I'll try out that noise filter

Man you are to fast!! Thanks so much. So this would go between the fuse box and the lighter right?

Yup...Simple install. I think that one is $5

Well I'll give it a try. Maybe get one of my electrician friends to hook it up. I'll post my findings.. Thanks again for the direction!

Or just plug your Droid into the XM receiver using something like Amazon.com: Griffin Noise Reducing Audio Cable for iPod, iPhone or MP3 player: Electronics

You know, its funny I was just thinking, that I have some magnets that I used to have that went on a VGA video cable that I dont use anymore. I wonder if they would work? Think I might look for'um and give that a try.. Thanks..
