Is there any way to fast-forward through a track that is being played through the USB input? If it's connected to my iphone, I have to open the podcast or music app and use the device to skip forward, which is not something I'd do when driving. If the audio file is on a USB flash drive, there seems to be no way to do this.

Am I missing something?
