I have an 06 5AT Navi. I removed the stock HU and installed a Pioneer AVH4100NEX. I like this head unit, but have to so some plastic fabbing to fill the gaps left. Question is, I would like to utilize the display area, and was thinking of doing the Nexus 7 install. Are any of you aware of any way to have the nexus display the output of the radio. The pioneer has bluetooth mirroring and navigation, so no need in dealing with the old pioneer system. Thanks. the radio uses one rca video output.

 

Figured it out. Should be easier than I had expected.
