Has anybody put a - Pac Aainis2 Auxilliary Input For Nissan And Infiniti - in a 2006 altima. (the device plugs into the back of the stereo, then you can plug mp3's into the device) I am not a techie, however I am capable of most simple techie tasks. I just want to know what problems you might have faced, or equipment I would need. Any directions would be welcome
