Tutorial: Updating The Traffic Receiver Firmware Software For Garmin GTM21 GTM25 GTM26 GTM36 GTM60

This will also work on other models of Garmin GTM traffic receivers as long as the receiver is compatible with the Garmin GPS through which the update is executed.

You have provided a WEALTH of knowledge.. Thank you so much 😀😀👍👍

Another excellent video from you. Few questions: A. Does the GTMxx number provide any hint as to what geographical area it includes a traffic subscription to? My ancient TA20 cable seems to have a bad power connection and I am looking for a replacement that supports HD Traffic (I shall use it on a 2595LMT) B. The dash mat in your video seems to be a different and more compact model than my wider and heavy bean-bag Nav-Mat friction dash mount...which also ran into extra scrutiny from TSA when I traveled with it! Any tips/links on how to find the mat model you are using? Thank you.

Thanks for the very informative video on the firmware update. I posted a question on your other video regarding the differences in the GTM and the TA cables and the Lifetime Traffic firmware updates. This video kind of addresses some of my question. However, Garmin seems to have models that are LMT and LM. The latter being that, I assume, no lifetime traffic firmware updates? Likely, this is because the necessary Traffic cable adapter (GTM or TA car adapter cable) is not supplied but with only a normal mini USB charge cable. So, my question is, for Nuvi units such as the Nuvi 2595LM:
1) can you have access to live traffic with the proper GTM/TA charge cable?
2) is firmware update available for the LM versions?
3) which GTM/TA charge cable is necessary?
4) Garmin made things really fuzzy - what's the difference between using the GTM/TA cable, having a dedicated built-in Traffic Receiver, and having HD Traffic Receiver? Does the GTM adapter cable also have HD real time traffic receiver?

Thank you for putting these videos together and for the time to answer questions.

Hello dear !
Thanks a lot for this very interesting video.
I have a big issue though.
My trafic reception with my GT36 cable stopped working since I updated my Drive 51 LMT-S GPS using Garmin Express.
It works very well with the Smartlink app provided by Garmin (and using my datas on my Iphone), but not with the cable.
The cable is well detected by the GPS though.
I had hope with your brilliant solution, but unfortunately, no trafic or any other FM options show up for my GPS when I load Garmin Webupdater. 😞

I wrote to the technical service of Garmin explaining the issue I have since I updated my GPS with their Garmin Express, and they apparently never heard about such an issue. They just offer me to... buy a new cable !!

Do you know by chance if It is possible then to do a Hard Reset of the GPS and go back to the factory presets or previous firmware ? Or something else...

Thanks you very much.

Hi, I'm struggling with this one, but I think I need it. Both satnavs 1300 + 1310 and both GTM25 leads dtopped giving traffic info at the same time (about). Your post isn't that old at 1 year, so I'm guessing both are ok (we cross tested) and something changed in our updates, or traffic provider. I don't have all the options that are listed (both UK set-ups). I used Express for years and didn't remember Updater was there before that. I only have language and a text listed in the updates... no Traffic Firmware types at all. Any suggestions? Help? Tips?

WebUpdater doesn't show the traffic update, what do I do?

[jayprakashbarot]

My question is I have Garmin drive smart 61 gps. I am currently living in chicago, Illinois and I am moving to Georgia in 2 days, will this GPS work there?
Please answers me sir thank you.

This is amazing content. Liked and subbed. I found this video because my Nuvi 2595 stopped receiving traffic altogether. It keeps saying it is searching for traffic providers anywhere I go. So google sent me here during a search. If I update the firmware as you show do you think it will cure this problem? Also the battery is nearly kaput. Should I replace the battery first or is it OK to just power the GPS in the car with the cable?

[jayprakashbarot]

[pcheintz]

You put out some good Garmin videos that have helped me... both this one and the battery replacement one. To name two. I do have a question I've not found the answer to yet though anywhere. I've 2 Garmin 255w's that I picked up used, and both now have the newest software for them (7.8) per both Garmin Express and Garmin Web Update. However, When going into their about screens, while they report 7.8 for the software version, the one reports GPS SW Version 2.00m and the other reports GPS SW Version 4.10b. How do I get them updated to the newest GPS SW Version? Or is that non-user upgradable?
