can i put an 04 navigation in my 07 g35 does it all just bolt in or do i have to change something

 

I dont know why you would want to do that. You have the updated interior in your 07. The 04 has the older interior and the screen is not even motorized. Use the search option , there are thread on people who have installed OEM navigation systems. I recommend buying a navigation from an 05-07 G35. Or better yet just buy the Double-Din converter and buy an aftermarket system. They turn out clean. I only bought my car with the oem navigation b/c I found the motorized screen too sexy when you start the car.
