Ok...So I am thinking that not getting the Nav system might have been a mistake. First off anyone that has the nav system please let me know what you think? Do you use it? Are there other things besides the nav that makes it worthwhile? I haven't been able to even see one so it's hard for me to justify the nearly 2k upgrade.

Second, if this is something that I want to get in the future how hard is a swap out? Will I miss out on features by not having it installed from the factory?

Any info or insight you guys have would be greatly appreciated.
