}
routeOverlayView = [[UICRouteOverlayMapView alloc] initWithMapView:mapViews];
diretions = [UICGDirections sharedDirections];
diretions.delegate = self;
}

[self.navigationController popViewControllerAnimated:YES];

endPoint = [NSString stringWithFormat:#"%#,%#",routeObj.latitude,routeObj.longitude];
destination = poiObj.english_title;

In UICGRoute.m
Replace this
NSArray *stepDics;
NSDictionary *k;
for (int i = 0; i<allKeys.count; i++) {
k = [dictionaryRepresentation objectForKey:[allKeys objectAtIndex:i]];
if ([k objectForKey:#"Steps"]) {
stepDics = [k objectForKey:#"Steps"];
break;
}
}
with
NSDictionary *k = [dictionaryRepresentation objectForKey:[allKeys objectAtIndex:[allKeys count] - 1]];
NSArray *stepDics = [k objectForKey:#"Steps"];
