I have a 160G SSD in the glove box that is always connected to the USB input. Every time I start the car it switches to the USB input. Then I have to manually select radio. It remembers the last radio station you were on. It remembers the last point in a song on a CD you were on. It remembers the last point of a song on the USB device you were on. Why can't it remembers the last input you were using?
