I guess what I am not getting is where do you connect the wires to? I have seen one post that says you have to connect to the power and reverse wires. Another to the back up lights. I can figure out how to route the wire, but nobody has shown how it connects. Or, am I missing it? Are the 3.0 and the Nav2Go 2.0 different in how they connect? I am gathering the 3.0 plugs into the radio and the camera plugs into the Lockpick? I would like to save $100 by getting the Nav2Go. They sell it for $169 + another $20 for some connector. Still trying to piece this all together.
