Hi guys, 
  
I have a 2003 model 350Z with the multi changer all in the head unit and I need advice on what to replace it with. 
  
I don't care about the multi changer.  The reason for changing would mainly be so I can connect my iphone to it. Secondly better sound.  If I can get my phone's sat nav to work through it on the screen that is a major bonus. 
  
Max budget say 3-400 in total? 
  
It's a double height unit of course so I'm guessing I will need a facia too and I want to retain the steering wheel controls. 
  
A guy told me you can get one with a connection for an iphone with the lead in the glove box but the glove box is far from the head unit in a 350. 
  
Happy to get it fitted professionally rather than botch it myself if its hard to do. 
  
Suggestions?  Tips to get round known pitfalls? 
  
Thanks in advance!
