Hello,
I have navi in dash mirror something like http://en.yftech.com/RA02-5002.html (RA02-5002) with front and back camera.
I can download only China map from application and also everything is in Chinese language. I don't know if it's possible to change firmware to have english language (if it is please help me with this) but for sure I wanna have map of europe.
Firmware version is ra02l.evb.160518
Android 4.xxx
