Yes it will do everything you described. only downside is, when you select the A/v to use whatever you plug into the video input you wont get to listen to the radio at the same time, unless whatever you plug into has audio out. the center button is the override button on mine
yes it will mirror your phone but you wont be able to touch the screen and activate the phone... you can only use the phone touch screen to perform actions. it has a video input so any video soucre will plug in, I plugged in a front facing camera.
I have that exact setup but I went with the wvity 01 which is wireless. Works great. There are a few different cameras on Amazon... Not sure which I bought but I think it was listed for tundra. . Regardless you will have to Dremel or drill out the bottom part of the emblem to get the camera...
