One critical thing to remember when approaching a roundabout is that traffic goes clockwise, not counter-clockwise. To go “right” at a roundabout, stay on the left as you enter the roundabout, and go around the far end of the traffic circle, before taking your exit; don’t immediately cut to the right at the traffic circle, or you’ll be heading the wrong way, in the oncoming traffic’s lane(s).
There's only one way on a roundabout, there's no oncoming traffic. In multi lane roundabouts if you want to take an exit on the right you stay in the right hand lane otherwise you'll be crossing the path of those wanting to exit prior to you and risk a collision.
Your gps app will know which side of the road you should be on and guide accordingly. I use Google maps or Amigo and they automatically adapt whichever country I'm driving in.
