I bought this to put in my Tacoma but never got around to installing it.
It would require modification of the bezel as the Scion units are a little bit wider than the Toyotas but it is plug-n-play other than that as the Scion head units use the standard Toyota plugs.
I have over $100 invested in this unit but it is not being used and needs to go.
$40 plus actual shipping.
PM me if interested.
