Question: Which cables does the 2597 GPS come with
Document: I bought a 2597 serial 2ZD148533 on Jan 23, 2014. I had it plugged into the car 12vdc power source. While on my first trip the screen would dim to barely readable then go dark. The voice directions continued with no problem, then the screen would come back in, usually within 5 minutes. I work with radios and amplifiers and this is what our products do when they overheat (i.e. turn down power for self protection, then when cooled off return to normal).
GPS systems have come along way. It used to be the smartphones had better GPS,but not anymore. Very easy to use and at e very reasonable price.
The GPS is not as easy to remove from the base as with the 765T.But these are both nits versus the updated features and usability. I only wish it would have come with the HD traffic receiver instead of having to purchase it separately - which I did.Overall, I am very pleased with this version, and highly recommend it.
Not a very clever design if you think about how you hold it.-What bothered me: Unlike many electronics, the device didn't come wrapped around a nylon bag. Weird for a new device.Bottom line: Yes, GPS works, but it is slow, impractical, and design/construction flawed.
Used the phone map for a very short trip and totally maxed out my minutes. This GPS seemed to be a good option. Even though this unit was supposed to come with the latest map updates, I did a new download just to be sure (don't know how long it was on the shelf before I bought it). It did not recognize many of the new streets that my other systems recognize.
Been running Garmins for 12 plus years now (marine, trekking, and multiple autos), kept the 245W for over 6 years. We are now living in a area that doesn't show up on my old GPS and the cost of the map upgrade (which in the old days they used to privide for free) made me decide on a new device. In summary, the new systems have come a long way.
Why is this a big deal? Well, if you don't know or have the exact spelling the the street you are looking for the GPS will come up empty. Example: The other day, I was in Jersey City, NJ and I was looking for the intersection of 7th street and Coles St in Jersey City. At the time, I spelled Coles st, C-O-L-E and the GPS said it could not find the address.
I purchased this Garmin because of its high rating on Amazon. I travel by car frequently for business, very often the same route between Maine and Massachusetts. I bought this Garmin more to keep track of time between destinations and for traffic avoidance as my new Yukon didn't come with GPS. The directions it gives are far accurate. When I leave my house it tells me to head in a different direction that I know is wrong.
I have had this GPS for almost a month now but have used it to travel from Baltimore, MD to KY to Austin, TX. It has met my expectations and the traffic feature is much more accurate than I was expecting (mainly because my previous GPS would tell me AFTER I was sitting in traffic so I had come to not expect much from this option). The screen is a very good size and even when the Sun hit it, I didn't have any real issues seeing the directions.
This was the second time we purchased the bundle of Garmin GPS, Hard Carrying Case, and Friction Mount. The 2012 model Garmin 2525LMT easily clipped off the mount so it could be stored in a case, but the mount on the new 2013 model Garmin 2557LMT connects to the back and does not come off, so it cannot fit into a storage case. Garmin should not have changed their clip-on design and Amazon should not bundle a case that does not work with the new Garmin GPS.
Answer: Mine came with a Lifetime traffic antenna/vehicle power cable (vehicle power cable is the traffic antenna) and a USB cable for your computer
