This may apply to other TomTom models too, but I learned it the hard way with my GO300. To do a soft reset on my GO300 a straightened paper clip WILL NOT DO IT. This is because the paper clips are too thick for the tiny reset hole in the GO300s. I had to borrow a sewing needle from my wife. I was pushing down on the hole with a paper clip for 30+ seconds counting 1001, 1002, ... etc and nothing happened. And then I noticed that the paper clip was not penetrating the hole. The sewing needle worked like a charm and in about 2 seconds - didn't have to wait 30 seconds.
