I'm sorry if this has been answered before...I looked and couldn't find it...but I just bought my Maxima (2010) and the system doesn't seem to find my iPod. Anytime I plug it in it reads the USB and then just says Reading USB/iPod. When I plug in my wife's iPhone it works perfectly...could this be the iPod's problem (though it works fine everywhere else) or is it something to do with the USB/system?
