When I bought my Altima, I said to myself: "Self, you are a software guy. That entertainment/bluetooth system is just software. It sure would be nice if it had more features. Why don't you try and upgrade it". So I got to wondering if anyone had tried to install new firmware on a stock entertainment/bluetooth/rear camera system.
Thought I would put it out to the Oppo crowd. Would be an interesting project. It has a display and is software driven. Ignore questions of warranty violations, since I'm not ready to start pulling things apart just yet.
