I upgraded to a VZW Pre 2, from a Pre Plus several months ago. Recently I decided to use my old Pre Plus as a music storage device only for my Sony car stereo with USB input. This works great, except for the fact that I have to manually choose USB mode on the phone screen in order for the stereo to "see" the music files. Since I keep the old phone in the glove box, this can be quite the chore to select USB mode every time I start the car, or turn on the stereo. Is there any way to automatically force the phone into USB mode once the stereo turns on?
