Hi. I replaced my head in my 2008 AH20 Vellfire, with one of these.
It is a generic head off the internet, designed to replace the existing panel. My son fitted it for me.
You have to take the air con panel, the ash tray cover and chrome surround off the old panel and fit onto new panel. The latter just clips in place as the original. The actual head panel is only about 1 1/2" thick, whereas the the old unit was about 6" deep.
My son also removed the Japanese TV and road toll units while he was at it; the dash is a little lighter now and the screen is now the full width of the panel.
My unit can get several types of Radio signal and has two USB inputs. As I remember one is for digital audio (I use music on my pen drive), the other is for digital video, ie, pen drive, video camera/camcorder, DVD disc player, etc. It also has Sat Nav, Bluetooth, reversing camera, and numerous other items the old head didn't.
I think yhe screen is 10" too!
I looked for details of one, on line, for a friend of mine and there are literally dozens of the same and similar models for most Japanese cars!
I hope that this is a help?
