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.
