Pioneer is banking on navigation. The company has put a lot of resources behind that product segment, delivering two portable and three in-dash navigation models for the automobile. The in-dash models are the company's bread-and-butter, since they offer the user the most features with the convenience of being right where you expect: in the dashboard, where the factory radio used to be. We asked Pioneer to supply us with one of these units for a tech story, and Pioneer delivered. By the way, we shot this install in a Nissan Titan a little while ago. Since then, the AVIC-D2 has already been supplanted by the AVIC-D3, but they are similar enough for you to grasp the straightforward nature of installing this product. This is an overview only. You'll have to read the instructions for the complete picture.
