Hey guys, 
I want to activate Google navigation. For some reason I cannot activate the voice direction.
I've read some articles on EK but I don't want to risk anything by doing that on my own. Bought a new phone yesterday 
1). I know there are ways to activate - Guide me please.
2). Do I have to root my phone?
Got an International Samsung warranty so is it okay to just throw it away? Rooting is illegal? 
3). If I root it, I can also unroot it back right? Does that mean I get my warranty back??
Please leave your answers/thoughts.
