Firmware Update (v3.10) for GTMxx Traffic Receiver Type 3

That's a very good question. I know for a fact that after "updating" (the update that never took place) my GTM60 (Prod ID 006-B1399-00), the nuvi now reports that no update is available, because of the new values (GTM firmware version number) written to GarminDevice.xml: (Note that I had to add dashes to the xml code to get it to display somewhat properly on this forum)

It appears that the units that are not actually updated (no "Updating traffic receiver" message & firmware version remaining the same) have actually been updated in a way that the firmware populates the GarminDevice.xml file with the proper values so the "update available" no longer shows when running WebUpdater/Garmin Express.

IMO, in the scenario you state, the firmware from an entirely different GTM unit will probably NOT be updated using the same nuvi...that nuvi thinks it has has already been updated. Remember that it's the nuvi itself that actually updates the GTM unit.

But, since this is Garmin, you never know.

I understand about to early in the morning. All I saw was the 36 at the bottom with a question mark. Sorry about that.

I have a 2595 and use a GTM25 with it. It appears that after downloading and connecting it up, I did NOT get the update applied. Maybe someone can tell me otherwise, but here is what the unit is telling me from the "about" and GTM diag screens:

GTM Version 5.50
Prod Id: 482
BB Ver: 210
Sys Ver: 550

If I'm looking in the wrong spot please let me know. I did note I received no "updating" messages when I connect the unit to my traffic receiver. BAH!

The GTM 25 is much older that the GTM35/36 and the GTM60 so it's had many firmware updates along the way...this is the reason that the version number is so high compared to newer GTMs.

The "GTM Version" and "Sys Ver" should be the same, as they are here.

"BB Ver" is unknown to me and I can't check since I don't have access to my nuvi/GTM at the moment.

"Prod ID" is the GTM's Product ID.

If you had no "Updating" message after disconnecting the nuvi from the PC and booting it connected to the GTM, then no update was performed.

I find it odd that even the much older GTM25 is getting this "update" as well. This newest "update" is v3.10 while your GTM25 is already at v5.50. I guess Garmin is being thorough & updating *all* GTM units with this "phantom update".

It showed as available through my.garmin.com dashboard for my 1350LMT. After it was downloaded, I powered it up with the GTM 25 cable connected which came with the unit and it updated.

Apparently you got the "Updating traffic receiver" message? What GTM version number is displayed after the update? Check with the nuvi (connected to the GTM) under Settings>Device>About (or similar).

@Falcon9
The GTM firmware version WILL NOT appear in the about screen until the receiver is plugged into the cigarette lighter and it receives the Traffic Icon.
Mine reads GTM 3.10 so the update was completed.

I am curious to know if your Nuvi 1350 with a GTM25 did in fact update, unlike others who reported it was not updated. I suspect it did not update.

I'll try a hard shut down (complete power off) and then re-boot with the receiver plugged into the outlet and connected to the Nuvi.

My GTM 25 didn't update.

GTM Ver. 5.50
Prod ID. 482
BB Ver. 210
Syst. Ver. 550

I have a 2595 w/GTM60 and 265WT with GTM25

From what I can tell neither updated to 3.10.

To further confuse things, this page indicates that GTM25's are considered a "type 3" receiver, at least for the purposes of that update:
http://support.garmin.com/support/searchSupport/case.faces?caseId={e78504d0-28aa-11df-e1e7-000000000000}

Also, this is the link to the "non type 3" update... Version 5.50 is what is currently installed on my 265WT.

FWIW, another update to Garmin Express has been released: v2.1.10

Just to clarify... in the post above, both Webupdater and Garmin Express indicated that an update was available for the traffic receivers. They were installed on the the GPS's then the GPS's were connected to their respective traffic receivers. There was no indication of an update being performed when the traffic receivers were connected and powered.

That is correct. BTW, I tried again after a hard power down (non "sleep" mode) and still no update or update message.

It could be that because my 2595 originally came with the GTM35, Garmin "thinks" I need the update. I run the GTM25 that originally came with my 255 because I have an optional Clear Channel subscription added to it. I'm disappointed because I'm -certain- that the traffic took a performance hit after a FW update several versions ago.

downloaded OK - but?

Not sure if it's related - but my redlight camera warning chimes for 2 blocks AFTER the intersection

My 2350 model is included in this update.

Just updated my 2460LMT via Garmin Express.

I have GE installed on my PC and always on, it alerted me as to the available updates this morning, I was unaware of this thread or the updates.

I say updates because there were two, a unit firmware update and the traffic firmware update.

I just did the update. Told me it is downloading 2 files. Waited unil that was done.

Turned unit off and it now just keeps going "updating receiver software 10%" over and over.
Then comes "traffic receiver software is updated" and the whole crap starts over and over.Sometimes goes as high as 40% updated before it starts all over again.

As it sits right now it looks like the GPS is a brick or paper weight? It just keeps cycling between updating and completed but it really does diddly squat!
Can not even go to the map page or tools or anything else!

Tried to log on to Garmin again, but do not get the option to update the traffic receiver files!

Just out of curiosity, are you in an area you can receive traffic information? It may be waiting to see if it can see a signal before completing the update.

It may also be one of those times you restore from an update.

No FM traffic signals here, but the 3790 updated just fine.

Well my problem got solved.

I use a 110v to 12v unit that charges up the GPS. It worked fine doing the 2013.4 update for 3 hours.

But after doing the traffic update it apparently could not handle it.

Plugged the GPS into the car 12 volt outlet and it updated itself within a minute or so without a hitch.

Whew, relief!

Your inability to update I believe was due to the fact you were trying indoors and did not have a satellite signal and traffic reception.
Once you put the Nuvi in your vehicle you got the signals then the update completed.

I am in the middle of Mexico and there is no traffic reception. Unless maybe just reading a satellite might have done it?
Gracias

Were you using the power cord with the correct traffic receiver built into it when you were plugged in indoors?

It's impossible to switch the 855 and 3790 power cords. Each has a totally different polarized plug which only fits the assigned GPS.

Although no Traffic in Mexico, once plugged into the 12V vehicle outlet the Nuvi was communicating with the traffic receiver.

Enjoy your stay in Mexico and get home safely

Worked fine on my Nuvi 1490LMT.

on my 1350 LMT In the developer info, Sys Ver shows as 310.

Does this mean it was applied successfully?

In your previous post you indicated your 1350 has a GTM25 receiver. That model will not apply the update.

Looking at Garmin’s site, it indicates the 1350 came with the GTM35, that one DOES work.
Look at the tag on your receiver to verify the correct model number. If in fact it does indicate GTM25, go no further, it will not update.

If the label indicates you have GTM35 read below.

After the downloaded update, when you plugged your Nuvi into the vehicles power source, you should have seen a message indicating the update was in progress with progress bars, then a message displayed the update was complete. To easily check, plug the unit back into the vehicle, wait for satellite reception and the traffic icon.
Now hit Tools>Settings> and look for the ABOUT screen, if successful it should show GTM:3.10.

Let us know of your findings

Garmin would issue an available update for the 2x5 series (255WT, 265WT) that were sold with the GTM25 traffic reciever
Is there something I'm missing or not understanding ?

It appears Garmin has made the update available for many models, allowing for the update to be downloaded, but never installing it since the product ID number was not written in the programming of the update. I don't know if they will correct it, or it's not applicable to many models, looks like they screwed up advising an update is available.

Several users with the GTM25 have reported their units did not update. Please go back and read some of DorkusNimrod's posts and that should make things clearer.

My two 780s got the update.

Garmin dashboard through my.garmin.com indicated I had an update available. I uploaded to my 1350LMT. I hit the road and it did in fact go through the update with progress bar.

In about > software version, it does show GTM 3.10 and the receiver says GTM 25, so I think you're wrong.

Just updated mu 2595lmt will see if I notice any difference.

As far as this GTM update is concerned, I don't think anybody knows for sure what is "right" and what is "wrong". There seem to be differences even between the same model of GTM units. Apparently going by the posts here, Some GTM units of the *same model number* are getting the update while others are not. I believe the deciding factor is the GTM unit's Product ID.

This is probably due to hardware and/or firmware differences between units and this is likely the reason why Garmin is downloading this GTM update to *all* GTM units, regardless of the model number. Certain Product IDs both download & install ("Updating" message upon connection to the GTM) the actual update while others download it only but do *not* install it (no "Updating" message upon connection to the GTM).

In this way, Garmin is covering all bases, even if it is a confusing mess.

For my particular case (2595/GTM25), this probably makes sense. Especially so when you note that for my GTM 25 it's showing V5.50! I guess this means my unit has advanced features no one else will have for YEARS! (i.e.: you guys that are stuck with V3.10) (or I'm a guinea pig BETA tester. [uh-oh])

1490 with GTM25 updated to 3.10
1450 with GTM26 still on 2.2

I must be an idiot but when I follow the process to check the ID of the traffic recievers on both units, I cant get into the diag area. I hold the compass direction on the speed page under map and get nothing.

Garmin certainly isn't helping in this matter. From their web site, your 5.50 became available nearly four years ago and the web page

http://www8.garmin.com/support/download_details.jsp?id=1445

implies that 5.50 is the latest update and applies to all GTMxx traffic receivers.

As DorkusNimrod discovered and posted as the first post in this thread, Type 3 GTMxx receivers are different and the latest version is now 3.10 offered March 5, 2013.

More questions regarding these two Garmin links:

-As far as my web searching goes, Garmin does not identify what a Type 3 receiver (which models or Product ID numbers) is and to my knowledge has not discussed which of their receivers are not Type 3, leaving us to wonder if there are Type 1 and Type 2 receivers as well.

-My email contact with Customer Support a week ago revealed that the first line Customer Service folks are unaware of the issue and when I replied to them with additional information, I've received nothing back from them.

Garmin has left us hanging with conflicting web links and firmware update downloads to many (most?) folks that will not be able to use the update.

>>Re: From their web site, your 5.50 became available nearly four years ago and the web page...<<

This is true. My GTM 25 came with my 255W purchased in 2009. I use it on my 2595 because I have an optional Total Traffic subscription installed on it and Garmin verified that all traffic functionality was exactly the same as the GTM 35 that came with the 2595. Only diff between the two is power draw according to them.

You don't need to go into diag. mode to get this information.

Settings> Systems -> about -> software version or something along this line.

But if you want to for whatever reason:
To get into diag on these models, you tap on speed indicator to pull up the large speedometer, then hold the middle of the speedometer.

From there, go to developer info and there should be an entry for GTM.

Just some data for you pros trying to figure all this out. Sorry it's not much of anything, but here goes:

I have both a 2555LMT and a 1450LMT.

I downloaded 3.1 firmware update to both units via Garmin Express (v2.1.1)

Both units use GTM26 adapters.

I took units out to cars, plugged in, gave time to aquire traffic and satellite. Both units say GTM v 2.2 not 3.1

Took units back in house, hooked to computer, Garmin Express says no update available.

I have the GTM60 for the 3490lmt hd and a 3760 with the GTM35 and I did the update on both units - I received the updating firmware message for the 3760 but not the 3490 - the GMT version on the 3490 is 2.10 and 3.10 on the 3760.

was successfully updated to version 3.10 with a GTM25 traffic reciever.

Received an email from Garmin. They said v2.2 is right for my 2 GTM-26's that came with my 1450LMT & 2555LMT.

I'm guessing what happens is that Garmin doesn't necessarily know what product ID and model traffic receiver you're using, so the downloaded file includes a range of applicable product IDs, then only parse the upload only if yours is applicable range.

Just as there are multiple PCB versions within the same model GPS units, I expect the same with traffic receivers.

I connected a different GTM25 that belonged to a relative to my 2595 (previously took the GTM update via webupdater) and it immediately fed it the update. Suspect what is going on here is as stated above. There are multiple "sub versions" of the GTM25 and the Nuvi checks, and delivers the update if appropriate. After the update the FW version reads 3.10. My original GTM25 will not take the update.

Ha, DorkusNimrod rules! I think he was the first to suspect this added complication. But your message is the first I've read that has proved it.

It waste my time so much and I have to turn off Traffic receiver forever. But I am updating Firmware 3.4 now as of today July 4 2013.
I will activate TM feature again. I will let you know if we should use this feature on this device.

I just bought a 3490lmthd and hooked it up to the computer last night and updated everything. One of the updates on Garmin Express was the gtmxx firmware update (I have the gtm 60). I updated it, but like everyone so far has mentioned, when I connected the unit to traffic receiver, it did not update the receiver. I just checked and the receiver is still using firmware version 2.10. So from what I've gathered from reading this forum, when ya'll complained about this problem to garmin, they never did anything about it? Has anyone had any luck in getting the traffic receiver updated with the gtm 60 traffic receiver?

Makes sense to me. My 2495LMT is on GTM version 2.10. Both MyGarmin and Webupdater indicate no update available. I still don't know if the unit still displays green when there's no traffic available. Haven't been out of range for awhile.
