This work for me, I have being trying this instructions for a few days, it would not work, kept getting stuck a map download 1%, I finally got it to work, I was trying to force the install on my ext sdcard, so I was copying the obb folder to my ext sdcard, I finally tried copying it to my internal memory and it worked. Thank you all, especially modemakias, I live in Atlanta GA and traffic here is really bad, I have tried almost many legal gps software with traffic feature, including Garmin, Sygic BMW and Hyundai plus more, and none is good as TT Go, im planning to purchase it as soon as I get my new tablet. I hope this helps someone else, I also notice that the software and map are stored on my ext sdcard.
