This past weekend I did swap out the dash "tray" which came with our Agile for a dash "box" like many of you have. I know these are standard on many vehicles. While at it I convinced my wife to let me remove the "tacky" fake-wood dash kit that was on way to many places. Honestly, the stock looks so much better to me than the fake stuff that RT used.
Anyway, the box swap was super simple. Essentially pop off the radio bezel. Two screws above the radio, two more on each of the vent covers. Remove the 2 vent covers to expose the final 2 screws holding the old tray in place.
Still chasing some of the glue residue but will get it all off next weekend. All and all not a very difficult job.
