Alright, I am purchasing a 350z monday, my issue is, I have an AVIC-D1, the 350z I'm buying has the nav in it, but the nav obviously isn't as user friendly as the D1, my question is, how do I install it?...I know it sounds stupid but after lookin at the dash I'm not quite sure if I buy the kit from crutchfield to hold a double din, or is there something I gotta do with the factory nav?...can I just pull it out? Any help would be appreciated!
