Summary: I've planned to write a review for this device before but never got around to it. However, it has failed me at a critical moment one time too many. It's pretty to look at but it's overly complicated and has failed more than once to find an address that was readily available on google maps, etc. My advice is don't waste your money.
Summary: i don't really like maybe the the i received has a defect because it could not find an address while my galaxy note 2 had no problem finding the same address.also the reason why we wanted to have the nuvi3597lmt was because of the Bluetooth hand free which is not working at all for the gps i have purchased. for those 2 reason i can't judge it yet.
Summary: I have returned this item for the second time. I got one this summer and loved it. Then it started freezing on me. Screen would be delayed in redrawing. The voice guidance would keep stopping and starting. I returned it and felt I would wait until there were some software updates. I bought a second one in February. The same thing started happening. I sent it back and will not order another one. I would give this model 5 stars when it works.
Summary: I've been buying Garmin units for over 15 years now and normally buy upgraded units approximately every two years. I have 7 other Garmin units, a couple of TomTom's, and a Magellan (yes I am a gps fanatic). First of all, let me say that this unit does have some great attributes, but the negatives are sooo negative I am giving this unit 1 star. For example of a positive, Garmin FINALLY let's us know what street we are currently on, a feature that TomTom has had forever.
Summary: I ordered this Garmin model and it had all sorts of problems that I couldn't figure out. So I exchanged it for another and that one was defective as well. This time I just returned it and Amazon charged me a $70 restocking fee, which I consider outrageous.
Summary: After using for less than 6 months glitches showed up. Voice pauses when giving directions, also it freezes while in route. voice commands do not always work on the first or second try either. This is my second garmin and changed to this one because of issues with my old one. Which lasted about a year, after leaving it the car and it getting hot it never worked right after.
Summary: On my forth 3597 in 3 month and the day after I sent the last one back UPS the current one locked up, I couldn't even turn it off. I had to wait for the battery to die then plug it back in for it to reset. The 3597 before that kept stuttering at sentence beginnings. The one before that would just randomly turn off for no reason and so on. As great as the 3597 looks and all of its features it pained me to return the final one to Amazon.
Summary: After bought this Garmin unit, I found it has nice features and beautiful UI display. However the joy only lasted for 2 weeks. After using it 3 times, then one day after I turn it off using the on/off button behind this unit, this brand-new GPS never powers on anymore - I have tried every method I can think of to bring it back to life (pressing the power button/attaching it to the car charger/connecting it to computer using USB cable etc), nothing helps.
Look out for worldwide distributors! anything you buy from them cannot be returned!

Summary: Amazon is now doing business with 3rd party companies that do not allow you to return products. Worldwide distributors has a return policy that basically states 'anything electronic bought thru us cannot be returned', guess what? they only deal in electronics! Here's the story. My wife bought me the cheaper 2555 unit, when I tried to get the bluetooth to work, it didn't (thought it had it), no problem, we got it from amazon, I'll order the top of the line unit with all...
Summary: I bought this model as a repalcement car satnav as it came out top in the Which reviews. However I have now returned it as being extremely poor. It came with only Danish as voice instructions loaded. To get the traffic, it is necessary to have an aerial trailing across the car's windscreen and the mounts provided kept falling down. The traffic news failed to inform of standstill traffic on the M25 and jams on other A roads.
