In Switzerland (and as far as I know western EU) you only get it with the so called "Toyota Touch n Go" Touchscreen Radio. It is prewired and ready for Sat Nav, however if you want to use the Sat Nav, you have to buy the "unlock chip" from the dealer. But the head unit remains the same, even if you do not unlock the Sat Nav feature.
I have not found any information on who is the manufacturer of the radio, as it is not labeled and always just refered as a toyota head unit (however I'm pretty sure its manufactured from some other company)
Anyways, have not found a good picture of it, best I have is attached, if you need better let me know, I can take some tomorrow. Also found an ebay auction listing the same unit and giving some info on what cars it does fit
