Received the Garmin 3790T four days ago. I upgraded from a from a Garmin Nuvi 760. My first comment is Wow! The size and physical design of this beauty is amazing. That's the same word that comes out of most people mouth's when I show them my new toy. Physical beauty aside this new unit really is a huge step up from my 760.
The 800 x 480 pixel glass screen is incredibly clear and a huge enhance over my old unit. The multi-point screen works great. Everything about the 3970 is an improvement from the old 760.
One interesting point is the 3790 picks slightly different routes than the 760 used to. I assume this is the nuRoute/trafficTrends in action.
Hands down my favorite feature on the 3790 is Voice Command. When I originally bought this item I had concerns about how well this feature would work. Let me tell you it works great. I can navigate to some place, add stops or phone someone without ever having to pull over or take my hands off the wheel. What a huge safety improvement.
Another seemingly small item they improved that I really like is the zooming. The map zooms in as you slow down and out as you speed up. It does it very smoothly and provides the perfect amount of data for my tastes.
The traffic data is also very useful in urban areas and well presented. However this area contains my only complaint about the product. Using the traffic feature causes small little adds to occasionally pop up on the screen. They are unobtrusive and don't happen very often so far but I would prefer to find a way to turn them off.
All in all I love my new Nuvi. It is one of the best purchases I've made in years.

I've been using Nuvis for years. Was very excited to get the new form factor Nuvi so I could give my well-worn 765 to my graduating daughter.

Received my fancy new device and put it directly into service on a trip to NYC--my first time there after all these years of exploring the rest of the country.

Made it through the northward routes of PA into Jersey, and then found myself at one of the famous "Jersey jughandle" intersections and unsure which lane to take for the direction I wanted to go. And the moment I stopped, I looked at my beautiful new Garmin to find out my next move.

And right on top of the map was a damn Red Lobster ad, hiding the info I needed. Couldn't make it go away, couldn't see my map underneath. Let loose a stream of profanity. Then the light turned green, I began to move, the ad went away and I found I needed to be in another lane, but my moment in traffic to plan the lane change had passed.

Garmin takes the only safe moment to check your map away from you--the moment you are stopped. So the only times you can check your map are when you are in motion and should have your eyes on the road.

Who is the genius that came up with this garbage?

I knew this problem was going to be bad in NYC traffic. But this POS had me steaming before I even entered the city. Inside the Lincoln Tunnel, once again hoping for lane info to get to my hotel, up comes a great big ad, WHILE THE CAR IS IN MOTION, obscuring the directions I paid my $450 plus tax to have. I damn near caused an accident with the "tourist slowdown" needed to find the right lane in time to get there.

Once in the city, this thing was the very definition of useless, with ads obscuring the map every time I was at a standstill and able to look at it.

This is a beautiful little unit - very slim, large, bright screen. The voice command system gets things right about two-thirds of the time, which means you can get going almost as quickly using voice as you can using the touchscreen. It switches between portrait and landscape effortlessly. And, having upgraded from a Nüvi 670 to this, I appreciate the new nüvi features such as displaying speed limits and cameras. Having included lifetime traffic is really handy too.

The integration of traffic into routing seems smoother than prior Garmins, although I drove in "red" traffic today that was moving really well, so maybe it overstates the problem sometimes. The new "mytrends" feature, in which the unit gets used to where and how you drive, sounds nice - I haven't seen evidence of how it affects things yet.

There is also a lot of new environmental and fuel economy software built in. The concepts will be familiar to people who drive hybrids - you get constant feedback, and can also access a lot of data, on whether you are doing too much stop-start driving, too many bursts of acceleration and too much rapid breaking. You get fuel economy and absolute cost estimates, all of which is handy. However, I don't like having the little "leaf" indicator taking up screen space, telling me whether I'm being naughty or nice. I wish I could remove it in the display options! A firmware patch is needed from Garmin.

OK . . . now on to the PROBLEM. This thing has POPUP ADS. Yes - commercial popups, like "Crabfest at Red Lobster" and "Best Western Rewards - Get 1500 points" and "Unlimited lunch $6.90" that pop up while you are driving, and take up screen space, obscuring the damn map.
