You can't use your ipod .The head unit controls it . The interface allows you to do things like access playlists .You can listen to any artist's collection. So , if you have 10 "led Zep" songs , you can scroll through the artist names to "Led zep",press enter , then the songs will play in the order you have them on your ipod . You can set up types of songs and access them as well . It is a pain to figure out at first , but once you have the sequence figured out , it's great ! I have 1 group named " motown" and it plays all different artists that I grouped together . It was costly but I really enjoy my "tunes ". I heard that there were some problems with installation at dealers . One dealer told me that he did 3 and none worked . I drove 2 hours to get to a dealer that had a good reputation and it was worth the trip .If you want to try to install yourself , The install instructions can be downloaded from
WWW.courtesyparts. com . Go to the xterra page , hit interior parts , then click on the interface pic . On that page is the instructions .Good luck !
