I beleive I've make my choice. I am going with the D3, Now I have two options one pay someone to install the unit, or if someone would be so kind to give me step by step Avic D3 installation instructions for bird brains because that what I have when it comes to this subject. And is there a place I can go a view diagrams that will show me how to do this. I have a 2005 Ford Five Hundred with steering wheel controls and I would like for those to work with the unit. Also I will be adding the bluetooth interface also. Reading youll messages makes me feel like a real idiot. I have know idea when youll use this Avic termonology. Help Please! Or is there any help for bird brains?

If you buy from Crutchfield, they will send you all the instructions with diagrams and the right mounting kit you need. And if you get stuck, you can call them.
