Any idea where I can retrofit my 2005 350Z with an upgraded audio and a navi system?

you can take it to a Shop, or do it yourself. the factory head unit isant hard to remove and a double din head unit will fit perfectly in its place. also do you have a roadster or coupe? are you trying to keep the factory look? or going all out and making an IASCA car?
