VIN 0532, delievery 3/9/11. Didn't try AC, so I don't know if I would have encountered any problems. But I contacted Nissan CS on 4/2/11 to find out if I needed to the software patch. At that time, I was not given any affirmative answers. Paul from CS was actually quite helpful and did contact me few times after that. It was suggested that I can get the update done. I went to Furture Nissan in Roseville on 4/7/11 and got the update done. Local dealer didn't know what actually was done as apparently, Nissan did it remotely. Nothing was mentioned on the "customer" copy I got from them. Tom Ley from Future Nissan was quite helpful and forthcoming though.
I have 3NA0B now but don't really what was there before this.
