Would you be willing to share any details of what you did? Physical and/or logical protocols in place in the Clarion? Which microcontroller you used? Etc.

Even the smallest hints would be a huge jump start.

I noticed that the schematics on the first page doesn't reflect how the touch screen is connected.
Does it use the I2C, the GPIO or some other method completely?

And a question directly to Ingineer; did your microcontroller fake a touch screen input or did you send the command in some other way?

I would like to know as well. Im planning on adding in an extra USB, to connect the old SSD from my MacBook Air and another power outlet. I would love to roll all the mods into one day of work.

Can you tell me more about how the Around View cameras are hooked up? Are we talking about 4 analog video connections (RCA/S-Video)?

I'm working on installing 2 dashcams, but might opt for a larger DVR solution if it's easy to grab a copy of the around view camera video.

All the cameras are connected to a separate module that combines and "stitches" the four images together. That combines signal is then sent to the A/V control unit up front.

I have looked into adding a video input for the unit but the only device I can find is over $700.
Would it be possible to add an aux video in to the unit for less?

I want to use the video to connect my Android phone so I can use the new mimicsx2 device to control the phone from the nav screen.

Thanks

Why don't you use one of video switchers (http://www.alldatasheet.net/datasheet-p ... 2533D.html" onclick="window.open(this.href);return false;) to combine an back camera input + your's unit ?
