Hello, I have a 2011 outback, limited edition without navigation system. It does not seem to come with usb port. Is it possible to add usb port to this model for the purpose of listening to mp3 audio files (usb stick)? I looked at part 86257AJ201 but the website selling it said that the part for my car (based on vin) is 86257FG100. I already have that and it is only the 1/8" jack. If not, what are my options? I try to steer away from using the jack which would force me to use my phone while driving (+ wire mess).
