    Please forgive my ignorance. I know little of the inner working of Blutooth.

    I installed a new stereo in my car with bluetoth and use it with my 2G touch.

    I am getting some background noise though. I think some of it has to do with the volume on the stereo needing to be so much higher wich just makes it more noticeable. And the stereo is not quite top of the line either.
    Bluetooth audio transmissions are digital correct?
    There is a lot more noise when the ipod is paused, after about 10 sec of pause the background noise drops considerably. Does not matter if car is running or not.
    Any Ideas?

    Also my music collection is from many different sources and the volume varies a bit from file to file. What is the easiest way of adjusting the gain on the source MP3's? It is especially annoying now that I am using the Bluetooth. When playing some files I have the stereo maxed out and getting maybe 1/2 the rated output.

    You can right click your music files in iTunes and press Get Info.

    From their, you can modify volume levels.
    Now, is it a bluetooth FM transmitter?

    Like, do you put your stereo on a certain station to tune into your iPod?
    If so, see if theres anyway to adjust the station to one with less radio interference.

    OK Well im not so well knowlegd on this topic but i dont know if you have ever used an FM Transmitter but it does the same! So my guess is that there is probably a disturbance between the bluetooth link! My best advise is to buy the Aux plug and connect it directly!

    It is not an bluetooth FM modulator. The car stereo is being used like a bluetooth head set.

    Oh, okay, that helps a lot.
    Have you tried lowering the volume on the iPod itself in the 50-80% range?

    Then using the car stereo to manage volume?

    So its up to the bluetooth device (in your case car stereo) to manage volume?

    Does you hear clear sound when the volume is very low?
    If thats the case, right click all of your songs at once in iTunes, and change all the volumes to very low, then you can turn your car stereo UP and the sound wont get distorted.

    It is NOT distortion. It is background noise. In most songs with the stereos volume at max there is no distortion. The volume on most of the files wound need to go up if anything. But that is a separate issue then the background noise.

    I can hear it most, as I said with the ipod paused and no sound. It is greatly reduced with the ipod completely off.

    Thanks for your attempt @ help but we are going in circles here. Anyone else (with bluetooth experience) have any suggestions?

    I think that because the bluetooth stereo "isnt the best" is your problem.
