This is not a moan about the maps as such Just driven using voice guidance. In front of me there is a roundabout and I need to take the 3rd exit. This is also clearly displayed on the iPhone map. But the voice guidance tells me to take the 4th exit. I assume it is counting the wrong way up a dual carriage way as exit 3. Next I come to another roundabout. I need to go straight over this one (exit 2). Again the correct second exit is depicted on the map. The voice tells me to take the first exit. So if you are driving purely by listening to the voice - you almost certainly won't get to the destination, even if the map is right in the first place!!
