It was actually closer to 1.5 hours on the phonecwith Garmin. I will say that the tech guy was great! Desktop and my phone wouldn't play with Garmin Express. He determined that the version was a few times out of date. The rep asked if I had another phone and that seemed to allow the updates. It is now connected to our desktop and updating the North America maps. With our speed it will be another hour at least.
Fortunately we don't leave for our tour for 7 weeks!
