Pretty sure I suggested the FMIC, turbo, & new wheels as did a couple other people before you...as for the oem Nav I love it and would def suggest it!

 

I had a Kenwood DNX 7100 touch screen in my old Z. It was a great Navigation/DVD unit. Super easy to use with the extra cable connects your itouch to run movies or music through the unit. You can probably find them for a decent price now. It could use more points of interest but a update can fix that.

 

i like enjoying my car at all its stages, aka i don't like rushing performance mods. (that and i want to keep the oem warranty as long as i can manage). if i was Octane i would enjoy the gst tune for a while before going hard on more performance mods. there will be a time and place for my Gigi becoming a beast. for now, suspension/exhaust/audio/wheels/electronics are my priority. but once again, i'm a utilitarian college student trying to maintain my warranty.

--> stainless steel brake lines and aftermarket head unit! def not oem.

 

I agree, go in stages you will definitely enjoy the car more and learn the car better this way

 

My b, I was surprised Boone suggested those first since that's typically what most ppl start with
