ANDROID iGO NextGen_9.19.1.484935_kk_loli + maps on sd card

Guys, I'm frustrated.
I am trying to get my LG G PAD (V490) cooperate with Igo NextGen, sadly I am unable to.
I managed to get the app running, but no matter how many tutorials I have followed, I still cannot make the maps work on SD card.

All the necessary map folders have been moved to
storage/external_SD/addons/content/

I modify the sys file, tried many option
1) ;android_secondary_root_path="/external_SD/addons"
2) ;android_secondary_root_path="storage/external_SD/addons"
3) android_secondary_root_path="/storage/extSdCard/Addons"
4) android_secondary_root_path="/storage/extSdCard/addons"

Still, the app says there are no folders in there.
My app is installed in root, android/data/com*** and the usual
I want my maps on SD card, can't do it sadly.
I'm crying for help.
