The choice (for that was what the OP was maybe presented with) of where to route himself to, has a useful purpose.
There are several posts from bods, complaining that their device routes them to the middle of a town, when they don’t want to go there. We can only assume they have entered say, Matlock, when all they really wanted to do was get close to Matlock and then carry on to go somewhere else. The ability to chose ‘Matlock A6’ would be very useful to them as it would take them to that point (ie not into Matlock’s centre) from where they would be able to continue on to somewhere else. To them, the device would be a thing of genius.
The truth is, the devices - and sometimes their owners - are very clever but simultaneously pretty dumb. The dumbness comes in that the device can and will only do what their owners order them to do. Order the device to “Take me to X” and it will do it, as it has no choice. Similarly, if you ask it to take you to a very specific street address or to a more general post code area, it will do that to, too. If the owner just wants to go to the centre of a town, it will obey that instruction, without exception.
If though, down one way of entering or selecting destinations, the device has not received enough data from the owner as to the destination, it will throw up pre-set possibilities as to places the owner can chose from. In this example, the owners seems to have chosen ‘A6, Matlock’. To his mind, that means a point on the map where the A6 enters Matlock. To the device, that mean ‘On the A6 but not at Matlock itself’, it being unable to read the OP’s mind. The device, as it has been instructed to go to ‘A6, Matlock’ will do as it is told, as it has no other choice but to do so.
Had the OP entered, “Take me to Matlock’ in a different method, then the device would have taken him to the centre of Matlock, without a doubt, probably (depending on where he was starting from and his personal settings) routing him along the A6. He would then have been very happy.
So, yes, it seems that the OP’s problems are down to user error. He has now learned:
1. That you can enter destination instructions into the device in several different ways, up to and including just tapping on the map. Be careful just tapping on the map, depending on the level of zoom selected and the accuracy / pudgieness of the finger.
2. That some methods will throw up choices for the device’s owner to make.
3. That the results can / will differ, depending on the choice selected.
4. That what the choice the owner thinks it means, is not necessarily what the device knows it means.
5. That the device can only ever do what it has been instructed to do. It cannot on its own think to itself, “He’s asked me to do this but really, he probably wants me to do something else”. It is not in itself intuitive nor a mind reader.
Get to know your device, fat boy, and how it works. It is incredibly powerful and a bit dumb. So much so, it’s almost human.
