This version come with proper POI functions and speedcam warning. put it in SD card, never in residentflash.
I am from China , it is working on both of my PNA.
BTW, if you enable QSI and met with major navigation window gray-out issue, just change your multi-navigation program launcher. I tried some beautiful Chinese/Korean launcher, haha, Garmin navigation guiding window grayed-out, and I had to roll back to some other popular launcher (system-info and miopocket both fine).
