Bests & Worsts Reviews from Amazon

Had the Garmin 3790LMT, which was a 4.3 inch unit , was the slimmest PND (at 3/16 inch) and Top-Of-The-Line back in 2011. This Unit has been thru frigid weather in Alaska, humid and desertic Mexico, as well the East Coast, West Coast and never failed. One of the gripes of this unit, was that after a complete shutdown, it would take about 2 minutes to find the satellite. The other gripe was Traffic Function was seriously impaired unless you had a 2.5mm Antenna Extension Cable hooked to the traffic receiver. Overall a 3.5 Star Product. The first thing that caught my attention after migrating, when I plugged the 2599LMTHD to my computer and ran Garmin Express to update the maps, I noticed that GPS arrived with the Internal Memory at 1.8GB free and 75% full. After updating to the latest map and other recommended updates, the unit ended with 1.7GB free and 77% full. The old unit, after 3 loyal years of service was almost full as well, but I eliminated all the unnecessary languages and keyboards and extras, I still managed to squeeze out 2.2GB free and 70% full. Perhaps the reason for the internal memory to come almost full, is that the maps are much more detailed and shows much more information, including WHAT STREET you are DRIVING on CURRENTLY. Also noteworthy is the WHATS AHEAD function, which is customizeable to show Banks, Fuel Stations, Restaurants, in your desired order. Positives: 1) 5 inch screen is much more adequate at showing relevant info of the surrounding area around you. It gets the same 2 hour stand-alone operation without charging as the older 4.3 inch unit, specially useful when plotting your next set of destinations at the hotel, without cables tangling you. 2) Spoken Directions are much more natural and sounds less robotic even at higher volume, thanks to a larger speaker (which by the way adds to the overall width of the PND at 11/16 inch) 3) Clean and intuitive user interface (classic Garmin advantage over many brands I have used), highly customizable screen and functions. 4) Foursquare app, where you can get reviews of fellow people, so you dont get punked at the wrong establishment at an unfamiliar location. 5) Pinch to zoom capability instead of tapping a + sign at the corner of the screen and re-centering the screen manually. 6) I specifically like this new function: you can point anywhere in the screen, and the unit tell you the exact address (specially useful when the address is sometimes off by tens of yards, typical in foreign addresses, OR when the address doesnt match that of google maps). In the old unit, you could only see the location you specified, and if you wanted to know what was the name of the next street and touched the screen, all you got was zoom-in the map. 7) Finally you can choose what type of format you want your coordinates to be shown, I personally like the same format as google maps, which is: h ddd.ddddd I was very frustrated by the different formats my old unit and google had, often times leading to different map outcomes. Now I can just input Google Maps coordinates, and the two outcome maps are the same. 8) Smartphone Link Capability also allows your GPS to communicate with your smartphone, albeit at a cost, to send Google Map coordinates directly to your GPS, as well as other functions such as advanced weather and traffic. 9) Fast link to satellite, around 15-20 seconds. 10) No more ads with Traffic Service. 11) Same great map coverage: USA, Canada and Mexico. Negatives: 1) Mini USB vs Micro USB in my old unit, with the need to pack 1 more cable during your trips. 2) Since the power cable is attached to the GPS at 90 degrees, rather than the mounting base as the old unit (adding to the overall width of the product), I find it much harder to detach and re-attach the unit. 3) No RECALCULATING message, they are useful in lonely highways, where the next exit might be 10-20 miles ahead, so someone can hear the warning without having to drive way too far before realizing they overshot their destination by many unnecessary miles. This is a contentious feature, as probably 50% of people love this feature, and the other 50% find it annoying. Hey Garmin?? Why not let people decide if they want to hear or not this message? Then everybody would be happy camp... 4) The internal memory arrived almost full (with internal memory very cheap, Garmin should address this), but with todays low cost of the micro-SD cards, it is a minor gripe. I suggest you buy minimum an 8GB class 6 or above for this matter. For having much more positives than negatives, and for advancing the User Interface as well as new useful features, all in all, a solid 4.5 Star product. Hope this Review helps potential fellow buyers.
