I also have a 2009 and wanted to be able to listen to internet radio or the MP3 player on my smartphone. I found a 2012 Versa radio on Ebay for $75 that had a AUX input jack. The radio was virtually new since it came out of Versa that had an upscale radio installed shortly after purchase. Another option I looked into was a ($160) adapter made for the radio that provided USB for flash drive and phone and a MP3 jack. It would also charge the cell phone and allow operation of the music player in the phone from some of the radio controls. Being cheap I went with the $75 rather than $160.
