hi I just posted on youtube a clip with me showing how to hack the nav system on a sorento 2011 (and not only). U can see me entering in winCE desktop enviroment, browsing files, running iGO navigation software with 2012 maps, running a video player and more. U can see my video on youtube
or just google kia sorento nav hack. All the files required for this to work are posted on a hyundai forum I put in the description of the youtube clip.Anybody with experinece in winCE can join in to develope and run different apps.
