Has anyone adjusted the music player presets and successfully improved the audio quality through the headphone jack (through a stereo, headphones are fine)? With the same setup in my car using the Bionic and Pandora, the music sounded amazing! There is clearly a difference with the RAZR, maybe less power driving the microphone jack if that makes sense, but I really miss my Pandora (and all music) sounding amazing through my phone and audio setup in the car.
