Hi everyone. I own a 2010 Nissan Sentra and a 3rd gen Ipod Touch (with 4.1 software), when I want to connect the Ipod via the Ipod cable to the stereo, the stereo screen says "reading files" but nothing comes up. However, there are times when it works, but the songs will lag and then they just stop but the time for the song is still going. It's so weird. What do you guys think I should try?
