I purchased the GTM-60 because it is supposed to give more detailed and up to date traffic information than the power supply cable that originally came with my DriveSmart 60 LMT. It certainly works receiving traffic information but I'm not sure at all it's any better than the cable which came free with my device. It's also supposed to receive weather information but except for one time in the month I've used it, the weather page on my Garmin has been blank One suggestion if you buy this, do not pay any attention to the instructions which say you have to register the GTM-60 on the Garmin website for it to start working. The web page it listed had no place to register it, I called Garmin and waited on hold for over 30 minutes to be told, "Oh, I don't know why they still have that 'register thing' in the instructions. You don't have to do that, it'll just work fine without it." She was right, so just toss the instruction leaflet in the waste basket and simply plug it into your unit.

Must have if you are an old school GPS user , and don't want to sync your phone for traffic . Very basic , doesn't update very quickly . A little pricey. Works just like the old ones did. Luckily I read reviews on the GPS I was buying , because they don't tell you that you have to have the special cord for traffic if you don't want to sync your phone to it .

I didnt have much confidence when buying this product but surprisingly works fine with my Garmin Drivesmart 51 NA LMT-S which I got 5 yrs back in Best buy. Happy with the product and I recommend for someone looking for basic traffic receiver.

I have a Garmin Drive Smart 51 model and i was using my phones data for traffic updates and conditions and it was working pretty good for a year and a half, but then my gps would start freezing and i didn't know what the problem was. I first thought that the device might need un update so i downloaded the updates at the time but it still kept freezing so then i reset it but that didn't work either! And then it hit me its the phone conection cuz when i turned off the Bluetooth conection and disconnected from the Garmin Smart phone link the device worked smooth no more freezing! But doing that unfortunately caused the device not to have traffic information! So i decided to buy the traffic receiver/charging cable, and im glad i did NO MORE FREEZING!!! Only downside is you obviously dont get all the features you would get if you had the data conection! But a must have just in case you don't have your phone for whatever reason......

Traffic receiver works great easy connect no subscription required. Eliminates using cellphone data. Should be included with GPS unit. Overpriced.
