Welcome, I also have the 06 SE 4 X 4, I thought if I was gonna buy the Xterra, I'd go all out! I paid 27,000 and some change. I probably have all the options and things you have. I have the RF sounds system which is very good. The splash guards and side mouldings were included along with the carpeted floor mats. I have since purchased the rubber floor mats, the carpeted cargo mat, and the sliding cargo cover for the rear. I also added an alarm with remote start and 35% tints on my windows. Keep me posted on how you like your X, and any options you may get, I'm always looking for new accessories.
