Sygic truck problem

I have sygic truck installed on my parrot asteroid smart,which i purchased through play store.I really like it but on a couple of occasions it has directed me the wrong way at roundabouts,ie take the first right instead of the third left!It thinks i am in france or somewhere!Anyone else had this and and clues how to stop it please.
