For those of you with the JBL system and connect your ipod through the USB port, does the car remember your last used audio input? In other words: say you were listening to the ipod through the USB port, you turn off the car, and then return and turn the car on, does the JBL system resume playing the ipod? For some odd reason, my car used to do this, but now it will start the audio in the "OFF" setting and I have to hit the Aux button to get the ipod going again.
