Question about the non nav "box"
 

Okay my question is can you take that and custom fit a kenwood 9140 double din nav in their or some custom guages in their or something Ive only seen one with something like that and it was a hin show so prolly custom.

my big thing is when i order my z in a couple of months should i go nav or not because I am not too fond of that "box" maybe because I am used to my nav in the jeep up high i dont know just a question,.

glassing would be required for the most part. i like what little storage it adds for me so i plan on keeping it. there are software driven guages that can display on an aux video input on a screen though as an alternative. there's a topic on here about it somewhere.

The one you probably saw was Amplified's, looked good.
I looked into aftermarket nav units in the cubby but the issue I found was the nav units will contiune straight back while the cubby slowly goes inward.

and garmin is coming out with a gps/gauge display soon too.
