DVD Nav Wiring Question.

As I have stated here before, I am looking to upgrade my head unit for the sole purpose to gain in dash NAV. I am wondering how hard the install would be to do this myself. Im pretty sure the main harness will be plug and play, but what about the steering wheel controls? Is that a direct plug in and go? Also the AUX / USB plug? Will that work with the main harness or will I need to cut / splice wires? And lastly.... how hard will it be to change the back up camera to the radio display?

Ok I know thats a lot of questions, but any help or links to help would be appreciated. Thanks

 

Can a brotha get some info in here? C'mon! You guys are slackin!

 

Need adapter for steering wheel controls. There are some good article on Taco Tunes on how to install.
