I do not have my Murano yet...I just ordered a 2004 SL with all options except NAV. I have a 01 Pathfinder I am trading in on it. I had to get an extra key made for the PF and they attached it to a special box under the dash. So when I press the button on the keyfob to start it, it seems like there is a key in the ignition. I just didn't know if the Murano had any other differences that I would need to be aware of before I got it installed.
