GPS stands for "The Global Positioning System". It is a satellite controlled navigation system made up of a network of multiple satellites placed into orbit. Initially GPS was only for military applications but latter on the system was made available to general public as well. The Global Positioning System works un-intrupted in all weather conditions and it serves round the clock.
Working of GPS: GPS satellites are rotating the earth in a specified orbit and they transmit signal information to earth. Signals sent by GPS satellites are recieved by GPS reciever which calculate the difference of signal timing sent and recived. The precise calculation determines the distance of reciever from the satellite. The user's position is obtained by a comparison of distance measurment with few more satellite. Electronic mapping reflects the user position which is displayed at the GPS device.

5Garmin Nuvi 3790T everything I expected and more
By WildBill
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.

5Excellent "Quick Release" GPS
By Truth Seeker
As a GPS Unit, the 3790LMT is phenomenal, and I'll get to why in a bit, but first, I decided to write this review for those who, like me, live in a part of the world where the climate is extreme enough to make it a necessity to take your GPS in and out of the car on a regular basis to prevent damage (or crime).

I used to have a Garmin 765T, which was a great little unit, for all the reasons I personally purchase a GPS. I don't care so much about playing MP3's or viewing photos, or even bluetooth, I just want a fast, accurate, and user friendly GPS. And, I've come to discover that I also NEED one that is easy to take with me when I leave my vehicle.

So, when my 765T's maps were out of date I was faced with a decision whether or not to upgrade the maps, or just get a different unit and I decided that for about the same price I'd "upgrade" to a new GPS that came with lifetime map and traffic updates rather than paying for a couple month upgrade to my old Garmin 765T.

After shopping around I settled on a TomTom XXL500TM. As a GPS, it was a good unit, but I immediately missed the "quick release" feature of my old 765T which allowed me to just pop it out of it's charging cradle on extremely hot or extremely cold days or when parking in areas where having a GPS in plain sight might tempt the criminally minded beyond what they were strong enough to resist. After a couple 20 second episodes groping around at night in the dark to hook up the charging cable and snap the TomTom into its cradle, I'd had enough and I sent it back. It was simply impractical for where I live. If you live where you can leave your GPS in the car most of the time without it growing legs, melting, or freezing into a sub-zero brick, then save a few bucks, but if you don't, read on...

Next, I began a search of the web looking for ANY gps units that had lifetime traffic and maps and some form of a quick release charging mount. That was literally all I cared about in terms of features, and I sadly came to discover that it was going to cost me a small fortune to get a GPS matching those simple search criteria.

Finally, after comparing mounts between the TomTom and the Garmin I broke down and tried the Garmin 1390LMT.

Same story, while the Garmin 1390LMT proved to be similar in quality to the TomTom XXL500TM in terms of response time and features. And while I did find its car charger and mount to be slightly easier to hook up in a dark car (maybe 15 seconds of fiddling around with the power cable and mount instead of 20), it was still a no-go.

That only left me with a couple other GPS models offered anywhere, by ANY manufacturer that had quick release mounts (at the time of this writing) and I was hesitant to spring the $499.00 sticker price (again, at the time of this writing), for a Garmin 3790LMT just for what I saw as "a few extra features" I'd likely never use, and a return to a somewhat quick release mount.

But then luck struck and I was able to pick up a 3790LMT here at Amazon for a little over 20% off and I simultaneously sold my old 1390LMT for more than twice what I'd just recently paid for it making the upgrade a wash. And what an UPGRADE it turned out to be!!

This GPS does what it is supposed to do, and it does it well. It's quick. It's sleak. It has great battery life. AND, most importantly to me, it has a fairly quick release mount (not the same old button release as the 765T, but it can still be done in a second or two using one, stiff, cold, gloved hand. And for me that's not too bad at all).

Added Bonuses:
I quickly came to appreciate the 3790's "voice command" feature. NEVER thought I'd even use it, and really didn't care one tiny bit about it when I bought it, but now I have looked up all my frequent destinations via Google Earth and entered their lat/long in as "Favorites" and using voice command I am quickly routing my next destination, and adding via points for coffee or gas, all while driving down the road, with my hands and eyes fully engaged in driving. On trips with frequent stops, the time savings really does add up.

Voice Command Tip: The Voice Command feature works nearly flawlessly with good diction, but even when munching on a snack (aka talking with food in my mouth... shhhhshh, don't tell mom), it has still proven to be almost "false detection" proof when using the numbered destinations saved in my "favorites".

Can it be improved upon? Yes.
1. Garmin could go back to the old button release mount they used to have in the days of the 765T.
2. Voice Commands could have more options such as zooming maps in and out, lane assist and junction view.

Conclusions:
I heartily recommend this unit as one of the best all around GPS units at the time of this writing. All opinions and brand preferences aside, it is one of the ONLY offered by any manufacturer at the time of this writing that can be quickly transferred from your car to your pocket and back as needed.

4Great unit - but intrusive commercial popup ads or "offers" that can't be switched off
By P. Lovett
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 $6.90" that pop up while you are driving, and take up screen space, obscuring the damn map. I called tech support, and they said that these are not supposed to pop up while you are moving, only while you are stopped. But these came up while I was driving today. Tech support says there is NO WAY THE POPUP ADS CAN BE DISABLED. Apparently it's built into the license with Navteq and will happen whenever you are receiving traffic information, and they cannot disable it. How is this OK? They don't mention it in the product specs, or on the box. I am paying hundreds of dollars for this device, and I cannot opt-out from popup ads?$#@!% Garmin seriously needs to get a firmware patch (or a hardware patch if it's part of the traffic receiver) out to allow people to disable this. The popups don't even have an "X" in the corner for you to press to get rid of them.

Having got that off my chest, I'm still happy, overall, that I bought this unit.
