It will not work. The one in the picture requires a digital external amplifier and since you do not have a JBL system, the amplifier and wiring is not there. Also, the dash opening is a different size (it's a bit wider on the bottom than the top).
^^First off welcome fellow fresnan! Hope to see you on the road..
To answer your question for the JBL, as mentioned above it will not fit, for the scion pioneer on the other hand it would be a direct swap for your radio.. i have it on my 4runner.
