I have read the wiki many times, in many different languages, since it is not a standard wiki across all languages....which is another example of poor deployment. I have never owned an android head unit but the main reason I selected Dudu was due to active software management. But I also think Dudu is sold as a premium product so it should be polished on all levels.
