Does anyone know of a pdf or other doc that is avail that shows the process of removing or even reinstalling the nav and radio of a 2012 Outback? I had to replace a cracked nav screen and from everything I read the unit should come out and have a bit of give. But i couldnt get it even a few inches as it seems the wires were way too tight and short. So was hoping there was a doc that could show me where I went wrong. thanks.
