I just purchased a car stereo for my Jeep, which is now installed. It has a USB port on the front of the audio deck, which is very convenient. I used my standard USB charger and plugged my droid right in. Here's the problem, when I started music through my music player, it just played through the phone speakers, and didn't play through the car speakers. I then pulled down my drag down menu, and mounted the droid, and it allowed the music to play through the car audio. The problem is that it seems it has to be mounted, in order for the audio to work through the car speakers. When the phone is mounted, as you know, I don't have access to the SD card... which is where all my music is. Does anyone have any ideas how to get around this? Aside from running a headphone to headphone jack, I'd really like to use the USB for sound, as well as charging, because the audio should be better than the headphone jack, thanks for any input!
