Great GPS but software interface not very intuitive.

Great GPS.  Software interface a bit difficult.  A little bulky but then again I am a woman with a little arm.  Would like if the battery indicator was on the main screen.  It would help me to know when I need to charge it back up.

Arrived super fast. Setup was a breeze. Product works great, just as described. The software on the tracking website can be a bit painful if using a cellphone to track the gps, but with patience it can be done. This is my biggest aggravation with this unit. Otherwise I love it.

It's great to use when driving in unfamiliar areas, although occasionally the instructions to "keep right" or "exit left" were too late or too early to be useful. But, if you're paying attention to the road, you'll see the signs you need to see anyway, and it does warn you about thirty seconds before you need to do whatever step is next. This unit does not speak the names of roads or exits, but it does display them on top of the map. It's  a little annoying to have to to back to the main menu to adjust the volume, especially when you're driving. When I answer my phone via bluetooth, I have to reach over, go back to the main menu, then hit volume, then hit the very small "mute" button, all on the touch screen so you can't just feel for it.

A couple of times, I've used it while traveling familiar roads just to see what it would say, and it does not always give the shortest or fastest route. However, it always seems to give the easiest route, so I guess that's a plus if you don't know the roads you're driving.

Overall, it works really well as long as you're not the type that relies exclusively on timely "do this right now" verbal instructions. for the price, it can't be beat.

I use a GPS all day long and this one took a little bit longer for me to input addresses and get the GPS to work.  It is a good unit, but I need something that works fast and doesn't take forever to figure out how to use it.

The screen is really nice. I like the Microsoft health companion app. Cortana integration and text/email notifications are really nice too.
The biggest con is that the GPS isn't very accurate. Seems to be anywhere between .25 and .5 a mile off. It's not a problem for me since I use my phone for the GPS.

Battery life could be a bit longer but charges fast. I get about 2 days of charge and charging time is an hour or less.

I like it for what it is.  Twice I found I was in a newer area, but the street couldn't be found by Garmin.  Then I recognized it had 2005 software in it.  That was not part if the description (a little bait & switch to me).

Love the dial to turn up sound.  Graphics are fine.  I have some trouble going directly back to a new destination (instead of pressing BACK multiple times).

Definitely beneficial for anyone who gets lost as much as I do.  There aren't that many new streets in my area, but apparently to update is very expensive.  This is a little false advertising to me.

I first bought this GPS several months ago when Costco had it on sale but ended up returning it because I was not pleased with the time it took to recognize my location.  More specifically, I would be on the Capital Beltway surrounding DC and the stern female voice would repeatedly tell me to make a U-turn.  Impossible.  I then used a friend's hand-me-down Magellan which would not hold a charge, not recognize the location and simply needed to be retired.  Enter Amazon and their great price for the Navigon 2100 max.  Since I'd read that the device was improved with the Fresh Maps update, I purchased Fresh Maps and I highly recommend you do the same if you're contemplating this beautifully sleek GPS.

If you have a PC, you are able to upgrade by connecting the GPS directly to your computer.  If you have a Mac, then it's a little more complicated but so worth the effort.  You need to remove the SD card from the GPS and transfer the downloaded software to the SD card with a card reader/writer and then reinsert the card into the GPS.  I kept a backup of the original software on my hard drive just in case, but have had no need since the upgrade immediately worked.  Now on to what I really like about this system.

The 4.3 inch screen is easier to view than the 3.5, particularly if you have many of the POI's selected for display.  I first chose them all, then realized they obstructed my map because I'm in the DC metro area.  Mine connects with a satellite in only a few seconds each time and reroutes immediately if I change my route.  Previously, it would announce that it was rerouting, but it no longer does that, just does the work.  Three choices for trip planning are fine enough for me, I tend to choose the Optimal Route.  I love being able to select different destinations, too, if I'm going to different places.  The address book is easy to access and locations are easier to save.  Traffic support is a great asset and now comes free with this device -- I've been saved from many a jam and not have to be tuned into the radio for traffic reports on the 8's.  I have the screen set to automatically change from day to night and have had no problem viewing the screen at any time.  With the new software, you are able to turn off the GPS from the touchscreen in addition to the usual power button at the upper right hand edge.  I love the 2D/3D view, especially when I'm approaching a multi-lane area and I'm unsure as to which lane I need to take.  Two voice selections are fine for my needs, Dagmar is more pleasant, but the higher pitched Sarah gives the text to speech option (TTS), so that's the one I've selected.  She's not very pushy, either, as some voices I've heard on GPS systems.  In the pre-update version, her voice sounded more Germanic, I assume from its origin of Germany, but it's not as odd now.  For me, this GPS is intuitive to use and I can make any adjustments from the touchscreen very quickly.  I've yet to have a freeze of the system and it has always known where I was with one exception when I was off road on a gravel trail.

My only real criticism of this unit is the rigid cord which extends straight out of the bottom of the device, being so inflexible that I sometimes dislodge it when attaching the mount to the windshield.  I'm not crazy about the mount either, but am trying to decide how to approach a new mounting system.  I do not want the display obstructing my field of vision but am not ready yet to get a sandbag type dashboard mount.  I'm thinking of constructing something myself using the little plastic disc which was included with this GPS system.  Also included is the USB cord, but no AC power supply.

We bought this because my son was making a cross-country trip. We began by hooking it to our home computer to upload/update the maps he would need. The Garmin Express software isn't very user friendly, in my opinion. But the unit itself works great! We were a little disappointed that an antenna (to take advantage of the Lifetime free Traffic feature) was so expensive (~$70) when we'd already spent a good deal on the GPS. So we'll postpone that purchase for a bit. During four days of travel, only twice did the GPS either confuse or not properly instruct him (my son). He wished it had a feature to "Find nearest Interstate Entrance" -- maybe it does and we don't know how to use it?

This device is great.  The only problem is that the software is a little bit hard to figure out.

The interface is a bit cumbersome to use and find out where things are at, but the connectivity with my Garmin 60csx worked without an issue.  I would recommend it.

I was attracted to the Garmin Street Pilot i2 based on the Garmin reputation for high quality GPS units and the bundled City Select North America mapping software. I have two cars that have DVD Navigation systems (Nippon Denso) built in and have come to appreciate the convenience and routing flexibility this technology provides. I also have three other cars that don't have GPS systems and find that I miss having access to the navigation reassurance I experience in my other cars. When I saw the price being offered by Amazon on this unit, the features, software bundle, portability and Garmin brand I was hooked to take a closer look. The Garmin information and the reviews on this page indicated the unit was a superb value and would give me the ability to move the unit from car to car and small enough to throw into my briefcase for out of town travel where I am frequently lost on first visits to new towns. The unit also has frequently updated Points of Interest (POI) that lists, among other things, numerous restaurants by proximity to where you are currently.

Upon actually receiving the unit I was impressed with the small size, the accessories and the build quality of the unit. I followed the start up instructions and booted it up. I did note that the i2 does take longer than other GPS units to acquire satellites - strangely much longer on initial boot up and less time on subsequent start ups. The instructions are not very precise on the set up options and I learned a lot by going through the detailed manual on the Garmin web site. The i2 is intuitive to use, so kudos to the Garmin engineers on having thought through the user interface. The unit is also accurate and provides good directions both on-screen and audibly. Battery life is about 6 hours on two AA batteries and Garmin includes a car power adapter so this is great. Using the scroll wheel for data input is a bit more difficult than my Nippon Denso touch screens but not bad once you get the hang of it. The i2 lost a star in my rating due to excessive time to acquire satellites, lack of easily accessible documentation for advanced set up and difficult to navigate Garmin support web site.

Couple of negatives that I needed to work around.
1-There are warnings on the Garmin web site that California and Minnesota do not allow devices attached to the windshield. I didn't want to put the included permanent attachment disc on the dash as that would lock the unit into one vehicle and likely diminish the resale value of the car at some later date. Work around here is to obtain a "Type S Universal Holder" sold on Amazon that is intended for iPods and cell phone attachment to dashboard airvent clips. I glued the permanent attachment disc to the holder and it works great. (I did end up putting some thin rubberized electrical tape on the metal "prongs" to increase the friction of the prongs to the plastic vents - now it stays put on bumpy roads.)
2- The Garmin i2 memory holds several states on the included 128 MB Transflash memory card. I serached the Garmin site and found references that other Garmin units had been tested successfully with up to 2 GB cards. I ordered a 1 GB card from Amazon for ~$40 and it should allow me to hold most of the US (otherwise you need to hook the unit up to your computer - delete states from the memory card you don't need currently and then select and load the staes you want to add) we'll see and I'll post an update if it works successfully (It does! I was able to load all of the US, Canada and Puerto Rico on the 1 G transflash card - only downside is that it takes about an hour to download into the unit from the computer - but I shouldn't need to again until the software is updated).

Overall I would rate the StreetPilot i2 as a great value from a respected company in GPS technology that will provide the accuracy, portability and flexibility that I desire in a GPS Navigation System.

I love this GPS.  You can't beat Garmin products and this one has lots of nice features.  The one annoying thing is the voice activated feature seldom comes up with the location I want.  It can be hysterical seeing what it understands.  I use voice activation on several other products and do not have the same issues.  I end up typing in the address before leaving rather than finding it on the go.  That's okay since the GPS has always reliably gotten me where I wanted to go.  I love the display especially the lane assist and the very realistic view of major intersections.  I have done the life time map update and it was very easy to do.  I like the saved places and the voice activated feature works great when I ask for recently found locations or want to change the volume etc.

I have been disappointed with my Magellan 2230T-LM, mainly because of a poor interface. My daughter has a Tom-Tom and the difference is night and day. The Magellan's interface is not intuitive, and I have had to muddle around to understand how it works. And I've had a nightmare trying to do work-arounds using Canadian Postal codes which use the form of AnA space nAn. They do work but are awkward to insert. Physically, the unit works quite well and am satisfied with the operation.

I also had a problem with a mis-named road. I ended up speaking with a map-maker at Tom-Tom (who provide maps to Magellan) to get it straightened out.

I save my biggest criticism however, for the software. It installed OK, but leaves a big TSR (Terminate-and-stay-resident) program that hogs quite a bit of my active memory, and leaves an icon on the screen - this, for a program that I might use once or at the most, twice-yearly; and I haven't been able to remove it.

I now realise that Magellan is simply not in the category of Garmin or Tom-Tom. However I must confess that that I would be interested in trying the Magellan 6230LM which incorporates a dash-cam and is competitively priced at $200.

Not sure I'm $200 brave.

The search interface is difficult to get used to (my previous Garmin was much easier).  When I entered San Pedro, it offered 200+ San Pedro's throughout the world, and San Pedro, CA was near the end of the list.  I later discovered that if you enter "San Pedro, CA"  the comma being essential, it then went right to San Pedro, CA.  Now that I am getting used to the new interface, it is not so bad, but still more difficult to use than my previous Garmin.

On the plus side: (1) The Garmin Express easily transferred all of my saved locations; (2) The telephone customer service was OK and fast: (3) The Cartography Department was very responsive to my email comments.

The unit works very well, it even found my Garmin Heart Monitor and display that information.  I have found several things that are not satisfactory with the unit.  When the unit is setup to display in English the compass screen displays in metric as well as the bike setup screen.  But my major complaint is that software provided with the unit does not correctly display the working information.  I have email Pyle's support asking if there is a firmware upgrade or software available that I may have missed that corrects the problem, but have heard nothing back yet.  I have read other reviews on this unit an they pretty much say the same thing great unit, lousy software and/or support.

Update 7/9/15
The support team responded with the url for the software update the next day.  Unfortunately for me my email spam filter placed it in my spam folder.  So I didn't see it until today (7/9/15) so I apologize to the support team for my previous negative comments.  Once I got the correct version of the software installed I am happy with how it displays the data.  But even though I have it configured for imperial units, the laps only display in metric, since I intent to download the data to another program I an not too concerned. As for the unit itself, I really like it.  I use this as a backup to my Garmin 401 Forunner and comparing the output I find that it is just as accurate.  I now would recommend this unit for an inexpensive alternate to some of the more pricier bike GPS's.

slow to pick up GPS sometimes, some distances aren't correct but overall works well.

I had an Explorist 600 and am considering buying another.  Helpful hint: They won't tolerate being run over by a car.  I found it to be an excellent GPS but found the support from Magellan to be quite lacking.  The lack of auto-rerouting is a bother too since I use it most on bicycle & motorcycle.  Overall A good Product.
