Replacing 200 Rca Input With USB input

Hi all,
Just wandering if any has replaced the red and white rca input with a usb input (actual oem parts)

I want iphone Connectivity but would rather keep in oem and coming through the bottom of the dash where the rca is.

If anyone has done it id love to know!

Much appreciated

I'd be interested in this too, mainly just to charge my phone without using the 12v socket.

You could do that pretty easily, fuse tap off internal fuse box to 12-5v converter then wire up just the power for the USB port.
