so i bought a 2004 enthusiast 350z. great car so far, just rolled over 100k miles and have upgraded the stereo. I put a pioneer AVH-4000P double din head unit, alpine type R 10's and a 1000w amp. love it! HOWEVER, the previous owner removed the navigation unit from the compartment just above the radio... i don't know where i can get one or what to put in there otherwise. ANY suggestions? thanks

 

Second screen maybe?
You'll see the nav units for sale occasionally.

 

Factory Navigation was not an option for the 2004 Enthusiast model. It had to be an aftermarket unit, which is easily obtainable.
