When I recently test drove a 2011 4runner with navigation, I asked the dealer a bit about how the media playback system worked, but the sales guy did not really know. Am I correct, that you can load mp3 files onto the media system's hard drive? In my case, these are most likely going to be not songs but talks. Assuming i can load the talks onto the hard drive, can I rewind them a bit to re-listen to part of a talk? How do you load files, via the (rather awkwardly located) usb port? Thanks.
