That could be my GPS!
The UK map is OK, but the map of mainland Europe does some funny things.
In Spain it tries to tell me to use roads that just do not exist - not been built yet.
This was rather troubling at the time as I was the first time that I had used that map and I had not yet got wise to its stupidity.
And only this week it just sent me round and around in circles* trying to get out of the town of Speyer in Germany.
*Only once until I sussed out that it was up to its usual tricks.
