I guess what I'm trying to propose is to find out exactly what needed to be added or replace to make this work. And no doubt it's just the matter of how much money and effort I'm willing to throw into this project. Don't get me wrong, I value you guys' input and will take them into my consideration. But at the same time, nothing is impossible to do. It all just comes down to how much of the car I have to take apart in order to install what I need.
Now, the main reason I am posting this up is because I am thinking of getting the 40th Anniversary edition 370z because it has all the extra so-called features I love which I would consider even more expensive to add/replace/replicate to a car that's not a 40th anniversary (i.e. Fully loaded Touring + Sports Package 370Z with NAV). Things such as Red stitching is one hell of a job to do to a car that came with white stitches. Red painted calipers is also debatable for someone to get a better aftermarket. Then there's the special "Quartz" paint for the whole car, and smoked black rims which someone can tell me I could bring it in to someone who can do powder coating - the list goes on and on....
Since I'm not too big wanting an aftermarket Nav system, mainly for 3 reasons:
1) the Nissan NAV is SUPER SUPER awesome....by far the best factory NAV i know of, even better than my Lexus IS beause it has touch screen and buttons in place (so no finger prints) & also has a lot of built-in integrated features such as climate display, etc - things that an aftermarket NAV will not be able to have
2) It ultilizes the compartment glove space for the display, rather than the double din locations beneath it (where the stock stereo sits) so you get better vision
3) It looks much better because it was DESIGNED to be fitted with the car to begin with. NO aftermarket NAV will ever look as clean as it is designed to be able to fit with any car. With it's restrictions in size, the standard double din space....they are not able to put a 7" display + other buttons such as a jog dial like the 370Z factory NAV can for the ease of use.
Not to mention, now I have to worry about people breaking my window, jamming screw drivers down my door lock, just to steal my nice aftermarket NAV system....I'm not ready to go down that path again especially if this is going to be my daily driver and not a show car. At least with a factory NAV, less people would go through the trouble to steal a factory NAV as it'll have less use for them unless they have the same car.
...call me crazy, but I much rather look for a solution and spend upto $2000-$2500 to replace my stock Bose head unit to replace with the factory Bose NAV system than to spend $800-$1200 on a super fancy after market stereo system. Besides, I don't really care to have a better system than the stock Bose sound system that's already in place.
Of course I do realize that there's a balance in realizing what's worth doing and what's not, and I'm not gonna be an idiot and throw $10K (if that's what it takes) into stripping the car or buying components to make the NAV to work. But right now I do have a feeling I could make this to work if I can get these questions answered. Plus, if others that are on the same boat as me on this forum are interested, I'd like to post a detailed DIY on this.
For crying out load, I've been on Mitsubishi Evo X forums, Lexus IS and all of them have a detailed DIY as to how to put a factory NAV in a non-factory NAV car....we can do it! The Mitsubishi EVo X even requiring taking the whole steering wheel out and cut holes into putting a mic and adding some additional wiring harness....but it's super detailed and they listed out exactly which parts (P/N) are need....and that's something I'm willing to provide if I do perform this job.
