the name of the head unit is Smarty Trend, they have a site smarty-trend.com
I ordered it there. They even posted the photos from my installation there. If you are interesting you can watch the photos in examples of installed units.
I have installed aftermarket Smarty Trend head unit in my Kia Sportage. It is working on Android system and I think it is the better system for a car nowadays. I think it will be easier and better for your car, than the old one sound/navigation system reanimation.
