OK bought 16GB SD card. Downloaded from site unlocked versions from this site, created all directories etc.
I didn't create the two files .unl and the other one. Works just fine. I dunno tho if all these files are actual needed. And I have no alerts for speed cameras
DNX9990HD navi system sucks big time. In comparison to older DNX8220 is day to night. It has half view-able size and half the info. Well done
