I just replaced my head unit from a 2010 FJ. The speakers went in the garbage but the head unit I have stored. The dealer and I am gussing would be around $400.00 or so.
By, By double din, hello single with some room for odds and ends. I would let my head unit go for $100.00 or so. What is it worth to someone. The value is in the heart of the one wishing to purchase the unit.
