I am searching as we speak ... but kind of hoping for quick reference or at least a quick answer

I am in process of searching for my ideal car white g35x with nav .... but almost ready to give up. Did find an 06 g35x w/o nav ... qiuick calling around the audo shops got me nowhere (all say it's aftermarket in-dash unit is impossible) .... is it true? any one had clean install on a portable unit? (preferably inside that pocket on top ...

 

Im sure you can easily get a portable nav mounted up there.... I would just go with a DD conversion and get a new headunit though
