XM Radio

[CAPTAINJEH 10+ year member]

I just installed an XM radio on a 2008 Jetta using the Aux input jack in the glovebox. The thing is making this awful buzzing noise or should I call it a steady hight pitched tone whenever it's on. It's not that loud but loud enoug to hear and annoy me. The owners manual says don't use 12v power to it if this is happening. Which is dumb because I have to use 12v power with the satelite radio. Any suggestions?? I can't use the FM transmitter because it doesn't work hardly at all. Anyone ever hear of some kind of filter?

Thanks, Jason

What XM unit are you using and how are you powering it? My XM MyFi had a similar noise when I used the cigarette lighter adaptor. I bought a standalone power supply from http://www.xmfanstore.com and now the noise is gone.

I'm using the Roady XT and have it plugged in to a cig lighter that I added from the fuse panel and hid back up behind the fuse panel under the dash. Not sure if that's the same thing as using the hardwire device from the XM store but sounds like it's not working the same way.

That sounds nearly identical to how I was running my setup. I bought this and it fixed the noise issues http://store.xmfanstore.com/hardwire.html

Sounds good I just ordered the power supply. I'll let you know if it works, my fingers are crossed.
