I'm looking to mount a female USB plug (and the little audio plug that's required for audio from video sources) behind my driver's seat so I can just plug my ipod cable or flash drive into the port whenever I need it. Of course, the standard 3ft cable on the back of the unit won't reach back that far.

This looks like the USB extender I need. It's got poor reviews though so does anyone know if there's another brand that makes similar ones to that, that are mountable and whatnot?

Also, are there versions of it that will fit the audio plug? The only thing I've been able to find is this, which looks like regular RCA, which I don't think is what I'm looking for.
