Most of the big dealers stopped selling it a while ago. I picked one up a short time ago from PAC-2000 for $225. I think they still have them. Google PAC-200 and then search for KDLHX550.
You can set the daytime and night time colors to switch automatically and as former NXMX5 said, there's thousands of colors to choose from. I use white in the daytime and matching green at night. You can even make a Chrysler or Crossfire logo animation with the software they give you. Makes a good start up screen.
You can even make it talk to you like an old Chrysler K car.
