I don't think the SAm 2580TV was ever bundled with a traffic receiver, but it says in the specifications that it's traffic compatible although there's no GTMxx listed under 'Accessories':
However the Quick Start Guide has this to say:Code:Please Login or Register to see the links
The FM traffic of GTM25/26 should work ok if the 2590TV can indeed use traffic. However those chargers only have output of 5 Volts 1 Amp and most modern Garmins [post-2010 models] need more current to both charge and run the unit at the same time. The later units GTM25/36 have 2 A output.

The big difference is in the power available as i said before. Newer devices are backwardly compatible with the FM TMC part of the GTM2x and GTM3x is otherwise basically the same.

Hello Neil, remember that I said about adding traffic and suddenly all disappear? I found the real problem, it is related is not the cable compatibility but internal problems of electronic cable, simply changed and he recognized RDS perfectly. Thanks for the comments above, I checked all the addresses and they helped me a lot and help those who have doubts about the internal behavior of these cables and their original specifications GTM Traffic.
To repeat: It works perfectly in a GTM25.
Hug.
