My 6250 Professional refuses to take me across the A75 in Scotland. This is the main route from my workplace to England that I deliver to every day. There are no restrictions on the road and it appears that it is only a tiny section of the road that it does not want to go over. When I first got my device it worked absolutely fine without any issues but then it suddenly decided it would not use the route I require. I have factory reset it twice but it is still the same. My device is up to date. Has anyone experienced this on their device and if so how did you resolve it?. Thanks.
