I am the new owner of a Silver exterior and Black interior 2006 G35 Coupe 6-speed fully loaded with navigation. Very little needs to be done to it. two dents, broken license plate holder, and a passenger seat recliner switch that reclines down and not up.

I just got one question.... If I have the Infiniti navigation, can I put in an aftermarket double din with navigation to have two navigations working at the same time? I mean will one interfere with the other for sound? Thanks in advance.
