I seem to have trouble connecting to my home WiFI, so kept getting error messages when trying to download the latest TomTom map update. So, I went to the website and downloaded the update to a USB thumb drive. When I inserted the drive into the car, I get a message telling me that the car must be running to do the update, it should not be in a garage, and it may take one hour. Really? You are supposed to sit in your car for an hour in the driveway or be driving somewhere for an hour to do the update? Am I missing something?
