koboililaVerified Purchase A Great addition if your GPS is set up for it. Reviewed in the United States 🇺🇸 on August 7, 2010Product Packaging: Standard Packaging HELLO AGAIN AMAZON FANS EVERYWHERE!!!!

See more HELLO AGAIN AMAZON FANS EVERYWHERE!!!!

So, a few weeks ago, my wife gets into her car, looks around for the GPS''S mount and cord only to find that they are not there; long sory short - some low life got into her car, took the bean bag mount, the power cord, and a cassette adapter for her mp3 player.

Replacing the mount and adapter is not too hard on the wallet; and we were able to quickly pick up a 12 volt power cord with a mini USB end from R+dio Sh+ck to hold us over for the GPS (hated it btw, the GPS detects it as being hooked to a pc and only after a minute or two finally displays the maps).

We got an idea what the cost of the cord alone was going to be a year or so ago when researching the GPS (model 265Wt) and were not looking forward to shelling out well over $100 for a new one. So it was a pleasant surprise to find the cord here at a decent discount.

Mind you, there was never a thought in our minds to just skip the more expensive power cord for a cheaper non traffic version; we like this cord a whole lot.

We ordered the cord from AMAZON, it came very quickly, was gratefully received, and already has been put to use.

Doing research, before we bought our GPS with the free traffic option, I read numerous reviews, here and elsewhere, complaining primarily about two things:

- The traffic service is Ad supported
- The coverage is not in every area.

On the first point (to the spoiled little anarchists out there) I would like to mention a couple of things some folks may have encountered: Broadcast TV & Broadcast Radio. The last time I checked these ''Free'' entities used commercials to pay for themselves. Not only that they do it in a VERY ANNOYING AND OFTEN LOUD BLARING WAY.

Not so with the ads I have seen on the GPS; in fact it has never been more than a little banner that pops up for a very short while then goes away again. Unlike a radio ad that you are basically forced to sit through before you can resume listing to the broadcast, or a TV ad that takes up the whole screen and again forces you to sit through it, the traffic banner does not take up more than maybe 1/4 inch of the screen, the maps are still there for you to see, the routing is not interrupted & no one is yelling at you to buy their junk. If that is too intrusive for you then either pay extra for a ad free traffic service or use your cell phone.

Which brings me to the second gripe people have: coverage area.

Do you condemn a cell phone manufacturer because their phones dont work in areas where there is no service??

I am old enough to remember TV before cable or satellite where you sometimes only had a few stations available to watch as well as taking long drives and having to scan the dial on the radio to find something to listen to after driving out of a stations broadcast range. Look at us now; there are so many options available to us with satellite radio, mp3 players, etc; you do not have to spend a moment of your life in silence again.

Like TV and Radio, the money goes where the people and demand are. This service is still fairly new and over time, as more and more people use it, the service will expand as well.

Pros and Cons......

Other than the cost of the cord I can not think of any real negatives; and even that is understandable.

As for pros, I really like how it gives you a heads up in advance of possible traffic jams ahead. Our GPS, along with the traffic icon turning from Green to Yellow to Red, even will say "Traffic Ahead".

The GPS then automatically directs us off the route we are on and takes us around the congestion and then back on our original route.

No matter how you slice it, dice it, or mix it - other than the cost of the device itself - the service is free. Although we always have the GPS on when we travel, if I had to pay a subscription fee, I would not use the service; I just do not travel enough in congestion prone areas to warrant the additional cost.

Although coverage is not 100% nation wide, where it works it works well; it has pulled us out of more than one traffic mess.

Extremely easy to use: plug it in and go.

If this cord gets stolen as well we will be back for another.

JPRenoVerified Purchase It works, with limitations Reviewed in the United States 🇺🇸 on August 23, 2009Product Packaging: Standard Packaging I found it very difficult to find information on how this works and what it does, so I took a little gamble based on the only review here at Amazon.

See more I found it very difficult to find information on how this works and what it does, so I took a little gamble based on the only review here at Amazon. After using it for a couple of weeks, I have to wonder if the other review is a shill--it would have been nice to know what to expect, not just "it''s great" sort of thing.

So I''ll try to pass along my view of what this can do and why it is limited (based on my experiences with a Nuvi 205)

You simply use this in place of your DC adapter in your automobile, making it essentially invisible to you (nice--no extra wires to run). As you are driving, it is a receiver of publicly broadcast traffic information for the area you are in (thus the service is free) "when available". When your Garmin detects these broadcasts, it somehow compares the information it gets with your location and planned route. Garmin puts a little traffic icon on you display, indicating how traffic will affect your travel.

The icon is color coded--Green for no problems, yellow for some delay, and red for major delay. I think Garmin takes into account the delays on your route in calculating the arrival time. It does look for alternate routes, and I believe that if it finds a better one, it will automatically reroute you.

If you tap on the traffic icon, it Garmin takes you to another screen with some options: 1. view traffic map 2: see traffic on route and 3: see traffic in area. Since there were no instructions provided with the product I''m not sure exactly how you''re supposed to use these, but I''ll share how I think they work:
1. view traffic map: This simply changes your navigation map slightly so that the bad traffic areas are highlighted (in yellow or red) as you drive. I don''t know why this is done as a separate map--why don''t they just color code the navigation map?
2. Traffic on route gives you a zoomed-out map showing where you are and where the traffic issues are
3: Traffic in area shows a list of all the major roads in your area for which there are reports and color codes them. I found this to be the most useful feature.

So that''s what it does (maybe it does more, but I haven''t figured anything else out yet), but how well does it work?

The simple answer is that the device does what it is supposed to, but it is limited by the information presented to it. I''ve used it now a few times in the Philadelphia metropolitan area, and on a vacation that had me drive up the PA Turnpike, to upstate New York, to Buffalo, Niagara Falls, Toronto, and Watertown, NY. For the most part, the information presented on Garmin was never any better than that which could have been heard on a local radio station.

The coverage did not seem bad--every metro area we were near did have reporting. The only places without reporting were pretty rural.

On the vacation, we encountered 4 separate traffic backups (in areas with reporting), only 2 of which Garmin knew about. The two that it knew about, it estimated our delay as about 1 or 2 minutes, but one was really 15 minutes and one was over an hour. The two delays that Garmin did not know about were significant--one was a half hour, and one was a closed highway that cost us over an hour (and made us miss a ferry we were scheduled for). In the worst cases, had Garmin had the information, I''m sure it would have given us a better route. It''s not Garmin''s fault, but it does show you the limitations.

So bottom line is that this device works, but it is limited in the information available to it. Is it worth getting? That is up to you--I like having some insight into what is going on around me, even if it didn''t change things for me. It''s kind of neat seeing the list of different roads and there problems--perhaps this will help more if you are a commuter in a major metro area. If you do get this though, don''t expect miracles--you''ll have to experiment a little and use it like I do--as a tool that provides some more information to you (albeit not perfect)--and not a say-all, end-all on what you should do. 298 people found this helpful Helpful

See more I purchased this to see if it would be worth saving the expense of purchasing a new unit with built-in traffic coverage. It easily lived up to this expectation. It installs easily (just exchange it with the existing power cord) and behaves as expected. Sometimes it takes more than the advertised five minutes to find the traffic information (but it always finds it within 10 minutes of startup). It adds some nifty features that I can play with (when I''m in the co-pilot''s seat).

The area coverage provided by the free NAVTEQ-based service is good for the most part. I''m a firm believer in you get what you pay for, so I was pleasantly surprised with the overall coverage on a recent trip to Milwaukee. It displayed accurate traffic delays as far as 200 miles away from metropolitan hubs such as Milwaukee, Chicago, Cleveland, and Pittsburgh.

The lone dink I have with this unit is the coverage south of the DC metropolitan area. It works well North of Springfield, VA (the southern point of the infamous Capital Beltway), but 5 miles further south, there is no traffic coverage? I''ve only been as far South as Fredicksburg, VA (about 60 miles south of DC) so I don''t know what the coverage is like south of Fredericksburg. This coverage hole seems odd since the coverage North of DC extends beyond Frederick, MD which is about 30 miles North of the Capital Beltway. Since I live north of the Beltway this isn''t a major problem for me, but if I lived south of the Beltway I would be disappointed with the performance of the unit since there doesn''t appear to be any coverage. 3 people found this helpful Helpful

See more I was paying way more than this costs, each year, to get real-time traffic updates on XM radio during hour-long metro-area to-from job trips. The quality of the traffic updates in DC-Baltimore region had gone downhill. I wanted out. So I sprang for this upgrade to my GPS, figuring that if it only provided occasionally useful real-time traffic info, it would be worth it over the long term. So far, my experience has confirmed that bet--arguably.

The traffic info as translated to the screen is not as clear and accessible as I''d like. Yesterday, the traffic info indicated, as I approached a bottleneck on the Baltimore Beltway, that the delay was only 2 mins. That was nice to know. And it was accurate.

To foresee and assess the nature and impact of heavy congestion, though, you shouldn''t be driving: You have to drill down for more info with taps on the screen. It''s not as bad as texting while driving, but it''s a lot more distracting than talking on a hands-free. If someone''s in the passenger seat, that person should be in charge of monitoring the traffic info and tapping the GPS screen to see what''s up ahead.

Here''s how they could improve the product: One-tap access to a screen showing Google Maps'' real-time traffic map for the road you''re on--with + and - icons for zooming in and out. If you have an iPhone or similar, of course, you could use that--but not while the car is in motion, please. 8 people found this helpful Helpful

See more Last summer in Las Vegas, the original GTM-25 cord shorted out and vapor locked my GPS unit. Thinking that it may be time to upgrade units, I started my search. Seeing the prices and what features I would get, the replacement Traffic Receiver unit was my next best alternative.

My Nüvi 1490T came with the GTM-25 cable. That unit was purchased at Costco in 2010. After years of service, the cable give out. Ordered this unit. What I received was a GTM-36 cable. Concerned, poked around to see if this unit was compatible with traffic reception in the USA. Long story short - Yes it is.

Others have complained that traffic alerts stopped coming up when using this replacement cable. I have not experienced this problem in Las Vegas (home), Phoenix, AZ or LA, CA. Driving through these areas, traffic worked the same as on my old GTM-25 cable.

The cable is an actual Garmin cable. It is not a generic knockoff like you may think.

If your Garmin unit is giving you power/traffic issues, this cable just may be the best alternative short of replacing a perfectly good working Garmin Nüvi unit. 2 people found this helpful Helpful

Replace the cable between the cars'' 12 outlet (AKA cigarette lighter) and the Garmin with the supplied cable.

The enclosed quick start guide tells you this, anything else you have to go back to your original manual for. You can use the traffic adapter without reading the book but you will be happier if you take the time to read the manual that came with your Garmin GPS.

The traffic adapter is only as good as the data supplied. You don''t get traffic data everywhere and some of what you get is wrong. In Atlanta it showed me the road I was on marked in yellow and little road construction signs on it. Looking out the window I didn''t see anything. A few miles later it told me to get off the Interstate. Up ahead I could see the traffic backed up. It redirected me back to the interstate after the problem.

Around my home in Chicago it has ignored some traffic backups and caught some.

Now that I''ve taken the time to read the manual I think I will enjoy it even more. 4 people found this helpful Helpful

See more I originally bought this because my Garmin didn''t come with the traffic option. It works alright but the areas you actually get traffic reporting on is limited. For our area it is only one major highway and that''s it but it''s probably more a limitation to where Garmin gets the traffic info from then this actual product. I have seen it show construction information on the screen from areas outside where it shows traffic and also weather conditions on occasion.

It doesn''t come with instructions but is very easy to use. It connects exactly the same way as the normal power cord that comes with the GPS. The GPS should automoatically recognize it and enable the traffic feature. There is no additional setup. If you need to know exactly how to use something refer to the manual that came with the GPS.

This should be obvious but make sure your GPS is capable of using the traffic option and that this is the right model. If not it probably won''t work. Helpful
