My original intention was to buy a Z without nav, but my 40th came fully loaded (in Canada). I have to admit, the iPod integration and other goodies that come with the Nav package are cool little add ons. Pre-2011 don't come with back up cam, so I bought and installed the group buy cam recently.

So, it's a judgement call depending on whether or not you want to spend an additional $6000. You can definitely add those functions in aftermarket later on, some of which will look and function like OEM, and others not as much. And, it can cost you less than $6000 to do.
