I found this page too And for me it works on Windows CE I think The desire to update is such that the radio has a very limited Polish language and after that it is rather worth having the latest version of the system
Discussion about updating an EasyWay EW6800 2-DIN radio. A firmware update link was shared for the EW6800, with a warning to use it at your own risk and uncertainty about the source of the files. The device appears to run a Windows CE-based interface rather than true Android, and it was noted that no updates have been available for years. The owner wanted the latest system mainly because of limited Polish language support. A question about switching the unit to Android was answered negatively; conversion is not possible.
