I have a 2005 LE and I'm playing around with the navigation system. In the owners manual, It shows an address book setting. I cant seem to find that menu. The truck is only 3 weeks old, not that it matters but I also noticed that the nav manual is also for a Maxima. Do I have to update my system with a new DVD or am I just missing something? The manual tells me to press the settings button and when I do, I only get 2 sub menues and that's it. It is supposed to be in there according to the manual. I guess anyway. Has anyone else tried to use this function? Can I get another DVD to unlock these other menues? If so, can I get it on the web or the dealer? Your help would be greatly appreciated. Thanks.
