This is for prewired systems and was on a 2007. It should work for 05+. I haven't had any issues with the mounting location of the antenna, which is far superior than the windshield mount unit they try to sell you with the tuner. You can purchase the tuner and antenna from Grubbs Nissan for a good price. $240 will get you everything you need! http://www.grubbsperformance.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=XterraAudio Here is a pdf of my install http://home.comcast.net/~mosi26/xterra/siriussat.pdf
