All right! There's been a few days now that I'm playing with the 3490 UI. A few features from the 3790 are lost, yes, but overall there's no way you should regret the upgrade. I can't tell if there's a loss of map detail as it is something I'm not able to judge due to my area not being awarded by Garmin for all the features my across the border neighbours enjoy (for what I read). Also, I can't tell anything regarding traffic coverage - all seems the same and I didn't buy yet the GMT60 to test for better coverage. So far the only cons I report are the fact that the responsiveness to the touch isn't so instant as before, I mean looks like that one has to re-touch the screen to select the option. I remember this was something I found awesome in the old UI, fast response. Could be my impression, though, as all this happens more while driving so I guess that I'm trying to pay more attention to driving that precision touch. Don't do it often, still I don't recall happening before. Another con has nothing to do with the hardware or software. My voice command still doesn't work for "find Places", "find intersection" and "find address". I'm presented with "this feature is not available for Canada in American English". Now either I fix it, don't bother or use a truck-load of rust-off on my �parler fran�ais� lol. I'll seek for help to fix it for sure.

Everything else is good, great, awesome, fantastic!! And the info we get is either more detailed or better shown. Once again I gratefully thank all of you that made this convert possible as it's wayyyy rewarding compared to buying a new 3490!
