However, one of the annoyances is that it is not overtly easy to switch between applications with the sat nav running as it runs in full screen and I couldn't find a way to flick quickly to another app. As far as I can tell, the only way to do this using the sygic menus is to close the sat nav down entirely. .. There seems to be a lag in the voice and maps. The old Nokia N95 sat nav maps were generally 'spot on' when the voice said, "turn right" you could guarantee you were right at the point that you needed to do so.
