After the Garmin Nuvi 3790T died, I was a bit disappointed in Garmin. Maddog, Abercrombie and I were 4500 miles into our trip, and we lost a bunch of favorite places, travel distances and times.
We are anxiously awaiting Product Support from Garmin to Resolve the problem. I’ll keep people posted.

with help from Garmin Product Support…
it turns out when I plugged it into the computer, I can turn it on after 20-30 seconds of the power on.
I also applied the web update.
I am awaiting feedback on how to avoid it in the future.
