Question: Will this work with a Garmin Nuvi 2797 LMT?
Document: Using with an older Garmin Nuvi 205W. Works like a charm, with no issues. I was leery  because of not knowing for sure if it would fit or work but its perfect.
According to the erroneous description, this is a Garmin part number 010-00838-00 and, per Garmin's web site, will work on a nuvi 1490. It is not this part number and, while it fits in the back of my GPS, it does not work at all. I don't know what part number this really is (it isn't listed on the charger), but it isn't what is described on Amazon.
I purchased this as a replacement charger for my Garmin GPS in my car, but it didn't work. Do not purchase this.
Other pseudo- Garmin power cables didn't work on my GPS ..this one does! It is FROM Garmin and does more than just turn on the machine..it actually recharges it!
After years of use, the power cord that came with our Garmin GPS didn't work so we needed a replacement before our next road trip. This worked great and arrived in plenty of time for our trip.
It is a Garmin charger, works great. Do not order generic chargers, they will charge the battery but they can't be used withh the charger plugged in. It puts them in the mode to connect to the computer not to be used. You can turn on the GPS, hold your finger on the batt symbol for about 10 sec. and it will go into setting mode then plug the generic charger in and then exit the setting mode and then the gps will work. You would have to do this each time you used the charger.
You can't go wrong with this charger. There are many cheap knock-offs out there that will waste your (small amounts at a time) money and (large amounts of) time. My time is worth more than the difference of getting a cheap generic charger that may or may not work on day 1, or day 31, or day 331.If you have a Garmin that uses this style charger, and your old one has broken or been misplaced, just get this one and drive on!
I have an older NUVI (2 years old) and went to get a replacement power cord. I found the one I wanted but it said there was a newer version of the cord and linked me to this item. It fits and appears to work fine to start but after 20 minutes, the unit begins to freeze and lock up. After three days of doing it (and doing it quicker), I did some tests and if I ran it on battery power, it didn't lock up at all. Clearly the new cord is just too much for the older garmin.
I was concerned that the fat, square GPS plug end was not going to work on my Garmin 62S- It works perfectly. The large square part actually mates with the GPS and prevents damage to the metal electical parts. (I purchased cheap-o cords in the past and the weight of the cord and bouncing around breaks the metal male part. This cord prevents it.Two issues: A) it is quite a bit more expensive but looking at the quality, it is probably worth it. (I was going through 4 cords a year).
This worked with my Garmin Nuvi 350, cord is a good quality. I liked this product and would buy it again.
Answer: This power cord does the job as far as powering the device BUT no traffic data is received
