On a long journey I see various messages about delays and so on, which are regularly updated.
My expected arrival time also gets updated.
I am not aware that it reports anything other than what is on my route.
Note that I update the Tom Tom about once a month. This helps with latest road works etc., and there seem to have been some general improvements.
There is a problem with the updates.
Every time it fails part way through, but you just tell it to update again and it completes OK. Weird.
