2004 Nissan Murano SL Radio

[nate1611]

I just purchased a 2004 Nissan Murano and the sterio was just replaced, however I cannot figure out how to load a disk. There is no "Load" button but it will not just automatically take the disk. Can anyone give me any ideas how this is supposed to work?? I feel like an idiot but I really need some help! Is this supposed to be a single disk changer or is the a multi disk? The dealer has ordered us an owner's manual but it isn't in yet so I am completely in the dark! Thanks for any help. nate1611
