Hey, i have a g35 sedan and the Horn, Navi and Radio do not work, any ideas as to what causes this and how to repair it.

 

Sounds like a fuse. Start looking at them.

 

You might try scanning through this thread to see if your problem is similar to theirs:

The radio in my 04x was bad when I got it so I had to get the aftermarket kit like they did but mine did not come with the stock NAVI so I don't know if that problem would make that stop working too.

 

Ya I plan on getting a double din but what about the horn?
