The Nav unit makes the interior look so much better, IMHO. I just bought the car with it because of the appearance (It flows nicely) plus features. Infact I skipped over the 370z Anniversary Edition because it didn't have a Nav Option (Just my preference). That being said, it integrates many features of the car into one place which I do also enjoy (voice command controls the nav smoothly and I have used it many times while driving, as someone as mentioned you can use this to access the features while in motion). I hate the way the non-nav interior looks. But then again that's me and I don't care about $3000 option (You end up paying "near" invoice for the car anyway) Cheap? No. But if money is an issue then don't purchase Simple as that. If you are cheap and don't want to buy it, then don't buy it (I find that post amusing!). The Z is a great "cheap" buy when you don't load it up.
