I love the nav, use it all the time.. i can't speak for others, but, Nissan/infiniti have some of the best OEM navigation systems around. The Z's system integrates perfects w/ phone/bluetooth/ipod and it's touchscreen.. NaV is accurate and very customizable.
if u can get it, you won't be disappointed.
