When I bought my nuvi 3790 device, a few years ago, it was not possible to transfer routes from MS to 3790 device. After one of the updates the problem was solved and routes could be transferred , but it lasted only some time . Since the beggining 2013 till now it is not possible to transfer routes to 3790, and I do not know what happened. So, I just transfer waypoints.
I must say,also, that my 3790 was faster when it was new. May it has a soft problem?
Thanks
