Having been told by my TomTom 6200 that there are two updates to be installed, including maps, I plugged it into my laptop, as normal, and tremulously started the update process. That was three days ago, since when it has failed on all occasions having only reached a different percentage of download on each occasion - the most it has achieved is 48%, after many hours overnight, before failing.
Now it has no maps at all, and never finishes completing a download.
Although as a navigational device, it is excellent, why is it that updating is such a nightmare each time? it wasn't much better with my previous model, either.
