Thisautoradio is1 din standard size and it's sold by Soundton or Eonon logo (mostly) over ebay. The only problem i met to install it, was the external border, because crash with the car consolle; i had to keep the radio just a bit outside its slot; it stays tight, no need to complete the slot installation.
you can see it on A class consolle


after some weeks of using it, I find generally a very good item.
Plays Divx, mp3, wma, dvd, vcd stored on DVD/CD (rw included), SD, USB.
The divx player has got the resume/memory of last position played function, very useful.
What i really dislike is the graphic of MP3 player because the character set is too small. It's ok for a 2 din display, as i have seen, but not good for 4.2" display.


Btw those are my conclusion points till now:
+++ GOOD:
read mp4, divx, mp3, dvd, vcd etc.
SD slot
USB
DVD/CD rewritable support
radio ok with RDS and 6 memory buttons on control panel
very good display (ligh, definition, sharp)
good sound and video
motorized panel with 3 steps of angles
bluetooth very useful
price (185 euro)

--- BAD:
MP3 graphic/characters (too small!)
folder swtiching only via touchscreen (not good while driving)
no night display function
the usb cable, when installed, makes impossible to eject dvd/cd
