0 ports (yes this is important to know) I contacted tech support and they were very nice. They walked me through troubleshooting

Summary: So here is the deal- I bought this and it arrived on time with no issue. I hooked it up to my computer to update it and my computer would not recognize it. It charged but was not otherwise seen by my computer.
Summary: I have used this GPS enough now to understand it's capabilities and shortcomings. I have recently completed a 2100 Mile trip to south Florida. The GPS works well on some intersections and gives clear directions as to the lane to be in, and if you have a turn approaching.
Summary: Tell you a funny story. I was trying out this GPS and I noticed Traffic didn't work. The screen said something about maybe the signal is weak or maybe there is no coverage in my area. I live in Aberdeen, Maryland. The coverage map indicates coverage there.
Best Nuvi, I've had, but would rather have a dedicated Google Maps or Safari GPS unit

Summary: Pros: * beautiful, large, bright display * attaches to mount magnetically, very easy to remove to take inside or put in another call and to put back on the mount, yet stays secure when attached, I was in a car accident where I was t-boned with enough force to smash in the side of my car and send the...
Good But Lacking in One Major Area - The Most Important One

Summary: I've been using mine about 3 months now. Took a recent trip to Alphretta Ga, an area unfamiliar to me, and found out exactly what the 3597LMTHD lacks. It lacks any common sense! Here are two examples. My trip started in Kingsport Tn, down through Gainsville Ga and on to Milton Ga.
Summary: Since this is a dedicated GPS navigation device, I expected it to have better features than my smart phone (Google Maps). However, I was disappointed to see that not much has improved over the last several years.
Not My Favorite GPS: Some Advantages But Several Disadvantages
J. Preuss, Amazon
27 March 2014
Summary: I bought a refurbished nuvi 3597LMTHD specifically for a drive of 1200 miles one way from Missouri to Florida, even though I have two other nuvi gps units. However, the cost of updating the maps on those two nuvis versus buying a new nuvi with upgraded features seemed to make purchasing the...
Summary: Display is great, most features are great and good value for the money. But the voice command is not so good. With any level of road noise the voice command is hit and miss, and forget trying to speak things like town names that can be confused with other words.
Summary: I have had my 3597 for close to a month. I really wanted to love this unit and am still trying to get there. I upgraded from a 765 which worked flawlessly for 5 years so that is what I base my comments on. I'll try to stay brief and list my likes and dislikes.
Summary: Review of the Garmin nuvi 3597 using the V2.8 firmware I started with a 755T, moved to a 2495, and now have a brand-new 3597; I should have stayed where I was with one of the older, more capable GPS's.
