leftcoastmark, May 23, 2012 I bought this last year and have really enjoyed it. The
docking cradle is fantastic - you don't have to plug and
unplug the power cable each time you want to remove the GPS.
The one problem I've had with this thing is that it will not
stay connected to my phone (blackberry torch) via bluetooth.
It randomly drops (then sometimes reconnects, sometimes
not) the connection after a few seconds up to about 20
minutes. No audible warning when it drops the connection -
just a notification on the screen for 5 seconds (which
sometimes I don't see). VERY frustrating.
Routing is good, though it does tend to take me down side
streets when a better, more arterial road is just up ahead.
Love the multitouch screen - way better than the older
ones. I don't have any issues with the glare on the screen
PDM, November 5, 2011 I've been using this unit since December 2010, and I love
it for many reasons stated here. The functionality, to
which I continually discover nuances as time progresses, is
second to none. That said, there are a few issues that I
consider weaknesses that the buyer should consider, things
for which I rate this a 4, not quite a 5. These are:
- Screen size: 4-is inches of screen size is a bit smaller
than ideal. I had a 5" screen unit previously, and that was
large enough for the details plus the maps to be seen
clearly. The screen clarity helps, but another half inch or
so would be ideal.
- Microphone sensitivity: Unadjustable, the microphone is
very tempermental. It has to be very quite for it to
translate words consistently, and you have to face the unit
directly and speak deliberately. With voice recognition and
microphone technologies where they are today, these
weaknesses are annoying, and affect voice command and phone
- Lane recognition: The 3790T often things I am on the
service road when actually on the highway and vice-versa.
This causes it to recalculate often, which is annoying at
best and challenging for those times when I am about to
exit or turn.
- Speakers: The speaker on the unit is very limited in
volume, While the speaker on the pedestal is better, it
could be a bit louder.
Great things: I could write essays on the excellent
features, but many are already covered. Some of them,
- very fast satellite recognition on startup
- complete trip calculators
- traffic integration is excellent. Every time I ignore
alternate routes due to traffic, I regret it!
- recalculation is fast
- self-learning one's preferred routes is a helpful tool
- regular map updates are critical and well appreciated
Kong, August 23, 2011 I bought my first GPS to replace a LORAN-C. That should
tell you how long I've been using them. I've had many, some
good and some terrible, but Garmins have always led the
pack. They have again. For it it is made for, automobile
navigation, this thing is just fantastic. It is blinding
fast to lock on even though I live in a valley and park
under trees. It can find places on remote West Virginia
country roads with astounding accuracy one day and take me a
quarter way across the country for a first time visit to an
address for pickup of an E-bay item the next. While at
first I did not care for the operating system it was because
I was trying to think of it as a hand-held multi-purpose
machine. That's not what it is. Its takes you down roads
to the place you wish to visit. It has an outstanding
system for doing this, combining intuitively easy to follow
(and hear) audio directions with great graphics and
visibility. I have had not problem at all with glare while
using it in two vehicles. As for the voice commands, it did
have some trouble when being used in my diesel pickup truck.
However it works flawlessly in our car. Background noise
All is not well though. When using the GPS in my wife's car
I had to run it on its battery. Her cigarette lighter
doesn't have power. Battery life is shorter than I would
like. I have both my screen brightness and volume turned
down to about 60% in the car so the battery life should be
good, but in just a couple of hours it went dead. I'm going
to fully charge it again tonight and run it completely dead
tomorrow to see just how long it really lasts.
One of the features that I didn't give a bit of thought
before I bought the machine is the hands free bluetooth
phone connection. I love it! What a great combination,
voice GPS commands linked to the cell phone for hands free
use. My phone is not one that Garmin lists as compatible,
but it links up and works just fine. All features work
including on-screen display of my phone's address book and
then voice commands to dial. This is a combination made in
As for size and fit and finish - outstanding! I thought it
might be a little small for my myopic sight, but I can read
the screen easily in either the truck or the car. Oh, the
truck is big and I am not so we are well separated. I can
reach it for touch commands, but I have to lean forward.
I am concerned about scratching the screen. I think Garmin
should have provided some sort of protective case for it.
It wouldn't take much, and I intend to find one soon, if you
buy one I think you'll want one too.
In the end if you are in the market for a GPS for auto
navigation I would certainly recommend the 3790. Mine has
the lifetime maps and traffic thing, which made sense for me
because I'm a freak about map accuracy - I demand it.
Eric, June 2, 2011 Have now had this unit for ~11 months and am very
unimpressed with the navigation. My old 780 was much better.
The 3790T is awful on Houston highways often directing you
to take an exit off the highway only to get right back on at
the next entrance ramp! It sometimes fails to navigate
highway interchanges correctly, e.g. desiring to go
straight: instead of proceeding straight through as you
would expect it will route you to exit onto the crossing
highway, take the first exit, u-turn, get back on the
highway, then turn back onto your original highway and turn
in the direction you were originally going. Just last week
I was driving North on US59 (~5 lanes wide each direction)
in the left lane and for almost *ten* miles the 3790T
thought I was on the off-highway feeder road a couple
hundred feet to the right.
The 3790T will eventually get you where you're trying to go,
but it rarely seems to choose the most direct or easiest route.
For the price Garmin commands for this unit I expected
*much* better than what I got.
