Hey all, I have a question that I have asked alot of people. I have a 2001 ford f-150 that I have a 500 touch screen double din radio in now. However a buddy just gave me a 2017 ford edge system both the display and the stereo. All the speakers. It is a larger display and I love doing custom fit stuff so that's not the question. My question is how much can I tie back into this thing and what would be usable. If it would be used how and which direction can you guys point me in.
