I have installed on a Galaxy S4 stock 6.01 and a Galaxy S8+ stock 9 and in both cases, with NDS installed on an SD card, I needed to put the obb file on both the card and phone in order to download maps etc.
I have just completed a 56 mile round trip and working perfectly.
When I tried again this morning, the voice and maps have been downloaded! It seems the server was down yesterday
Thanks!
