New Tom Tom 620 says it needs 19 megabytes in 3 updates. So I connected it to my phone. 55% through updating it had already taken 6Gb - Gigabytes not megabytes. I stopped it so it deleted all the maps and became a brick. 10Gb of maps later, it still wants the 19MB in 3 updates which will be another 10Gb?
Are they all like this? Is this normal for it to lie about the size of the update? 6GB and counting seems rather large. And then to delete all its maps because I cancelled the erroneous update?
