just because you don't think its nessicary doesnt' mean everyone should think its unnessicary. for some people like me. i drive 30-40,000 miles a year from trips out of state to jobsites for my work, and having navigation would make things allot easier, just because you choose to not buy the option doesnt mean it is worthless to everyone, use some sence. only downfall is the cost, haven't priced dvd navigation lately but generally you were looking at 1000$ for a good flip up screen headunit and another 1000$ for a navigation unit, so for the same price as the stock unit you could have the same thing well actually i'd bet the aftermarket nav was a bit better, plus an upgraded audio unit. only thing the stock nav has going for it, is the stealth install.
