I want a new head unit that i can use with my ipod and control my ipod with via the head unit rather than the ipod click wheel. I don't need anything mega powerful or ear splitting and don't want to pay a fortune. I've seen quite a few that look okay on the internet but I'm not too sure of everything I need. I will have a double sized hole where the old 2 head units are, someone told me I need a Nissan converter lead? And do I need extra leads or anything for the ipod? I don't want to buy something and find I haven't got everything I need.
