After reading your post, I tried signing in and was able to.
It did take some patience and a couple of tries.
My guess is that the site is pretty busy, with a lot of people trying to register their new Garmins today.
After I got sgned in, I clicked on "Register my product". My browser is trying to load the registration page, but it is taking forever just to do that. It says "waiting for ........" and there is a progress bar, but the progress bar is barely creeping along if moving at all.
Thank you so much for your response..All the same here..can get in but will not go to registration and times out before it does...i thought it may just be me...I appreciate your efforts and info. Merry Christmas :)
