Mirror Phone Display on Factory Nav Screen

[lovemyvq]

I've been searching around a bit trying to find a way to display different things on the factory navi screen. Ideally, there would be a way to display torque pro app gauges/readouts from the an android (or apple...I guess) to the factory navi screen. With the searching I did the only options seem to be hks camp2 (no longer produced but could theoretically be found used), madgen (no longer produced and even more difficult to find), and carpc's or raspberry pi type setups which aren't overly simple. There's another thread here from carbonsignal with some options but it doesn't appear to offer an interface for android phone user to connect the phone itself and display obd2 readouts.

So then I got to thinking what about mirroring the phone on the nav screen somehow. Which lead to searching for different cables to connect the composite inputs already in the car. Which is where something like this comes in: http://www.amazon.ca/HDMI-Composite-...glnk-ca-c47-20

Does anybody have any experience with trying different cables to make the nav screen mirror the phone? I'm guessing it's nowhere near as obvious or straightforward as I'm hoping lol. I saw a video with a lexus mirroring a phone display but it required chromecast, a converter, 2 android phone and hardly seemed worth it just to drive around.

I guess what I'm wondering is, can I display the torque pro app's readouts on the factory nav without it getting overly expensive or complicated.
