hi, first i have to say i know NOTHING about cars.... And it's stupid when i realize i have no idea how to play music on my iphone through the car's audio system..... i heared pepople saying g35 does not have a aux port, and i can just add a aux port like a cable line? does anyone have any idea how to install them and where to buy them? plus, my navigation system is not working either.... It can go up and down, but the screen will always remain black, no matter which button i press. And my audio system sounds a little weird, maybe some problem about the horn i guess. So the question is, does anyone who knows g35 a lot living around Los Angeles? My car is 2005 Infiniti G35. If you can help me, plz PM me, or text me 6265518968 REALLY appreciate!

As for the nav problem, I don't think I've seen anyone report a fix that didn't involve replacing parts that would have been cheaper to replace with a complete aftermarket radio that includes navigation, or interfaces with your smartphone to do navigation. You're not missing out anyway, factory nav is terrible. Especially with the aforementioned nav problem and desire for aux input and the wierd sound, it sounds like you're definitely a good candidate to just replace the radio completely. A guide for that is also conveniently found at the top of the forum:
