Thread: Using TMC in Garmin nuvi for free

As might be expected, Garmin also released a new firmware version for the GTM 60 that blocks traffic with JetMouse signatures. The images below show the version 2.10 that blocks these signatures. So is need a downgrade to version 2.00.
If anyone has this version and can do an upload (use attachament), would be great.
The file 006B139900.gcd is in the folder RemoteSw (.System)...
To recognize the version of firmware installed on your cable, check out our hidden page "Diagnostics Page"/Developer Info/Traffic Receiver Status and check SYS Ver (200 or 210). To enter in Diagnostic Page press and hold the upper right corner of the page of Volume or the center of speedometer in the "computer travel" page.

File have a real date when it was copying for back up! It was provided by Garmin in all European devices with HD LT and so it is not tested with JetMouse...

Giomen,
In the versions that I could test the GTM 26 and 36 with signature Jetmouse work seamlessly with nuvis 1xxx and 37xx series. Not work in nuvis with firmware 2012 as the 34xx, 35xx, 2xx5. For any doubt please see attached screens. The white screens are of GTM 26 and the black of GTM GTM 36, encompassing the firmware 2.00, 2.10 and 2.20. Note that both have the same HWID. Already opened the box and checked the receiver: gtm26 and 36 are apparently identical.
In relation to my previous post about locking of the firmware 2.10 in GTM 60 working with 3590, I still have not found solution. I modified the version 2.00 that was installed correctly in GTM60 but continues with the error 12 with blocking of traffic, by the way, exactly the same screen that appears in locked GTM 36 of this post. Very curious is that the GTM 60 with firmware 2.10 works perfectly with nuvis of firmware 2013 as in 3597. Very probably the Garmin recorded the blockage somewhere in the non-volatile memory of the 3590 or cable, that the firmware can not access. Still need to test the GTM 60 with another gps (3590 or 34xx) in order to better analyze..

Loly, the firmware 2.10 does not comes of update, it came with the new gps newly purchased in the United States. Thus, we can wait that soon the Garmin will provide this firmware to update. I hope that the downgrade method is also effective to solve the "problem" ..

Angelo I think this is what you are looking for.

G, If you add a JM sub for somewhere other than EU on your GTM60 could you not see if it's just not recognised to test it? [or you could add Suna for AU and mail it over to me]
