Has anyone tried to upgrade the stereo for the 2007 FJ Cruiser? I wish that it was available as a seperate option. I'm sure it sounds fine to most, but serious audiophiles would consider it lacking

. Any advice out there?
Also, does anyone know if the face plate is a standard double DIN?
My FJ is on order and should be here 4/20

...I'm just doing some initial research so that I can get the parts list together for my stereo installers.
Thanks, Jimmy
