Hello all. This is my first question and I'm new to this forum. Glad to be here. So I have a 2008 Legacy GX H6 3.0L AT, without aux in, what should I do to get it at bellow the 12V outlet inside that leather covered box behind the handbrake? I would'nt like to cut any factory wires, just plugging something in the factory installed radio, since it has the button AUX but theres no aux-in. Can anyone help me out with this issue?
