igo freezes on "starting"

[nasridine]

I was trying to igo myway 8.4.3 on my atrix 2. Downloaded the maps and pois to the contents folder. After I installed the apk, I launched it. However, it stuck on "starting". I did some google search, someone say it has to do with agps, I will need to disable that first. But I can't find agps, how do I turn it off?
