Well left it "updating" overnight and think it took this time. I never got the 'settings' on the tom tom icon at the right bottom to work or do anything. I noticed mytomtom site was saying updating a Via 125 not a 1530 model and was unable to change it. We will test on a short trip tomorrow. I did turn it on and it showed the proper location of our house. The sleep mode is a power saver setting on the PC that goes on after so long. Something on the TomTom website mentioned changing this setting. I can't wait until the next attempt to update!
Thanks WoodGlue.
