As most of us know the headphone jack leaves a lot to be desired for audio volume which affects the quality of your songs. When playing through the 3.5mm jack in my truck I have to crank the volume a lot more which raises the noise floor and causes more distortion in my music and also reduces the available volume.
I took some of the songs that I've loaded onto the Droid and burned them to a CD. From the CD I get MUCH better quality and volume.
I have been looking into buying a new head unit for my car with a USB input. I was wanting to hear from others to see if the quality is much better. (as it should be as good of quality as my CD)
Also, I was wondering if anyone know if there is any work being done to develop a plug/dock that would allow you hook up the Droid and have RCA and or 3.5 mm outputs
