I see from the screenshots that the fw of your gtm36 been updated, but the problem of tuning continues, showing that this was not the cause. Unfortunately, the screens that you sent does not appear your original signature of Traffic. Please send a screenshot of the remainder of the screen, rolling it. The signature of your country (9/e4/1/33) must be listed. I should also note if others may have similar parameters and confuse the tuning (in this case it would be nice to erase).
But what is evident both in his case, as in the Ge_force, both receptors GTMs working, is that the parameters of the Radio "FM Table" are different from those included in the signature (which appear to be the original), so no tuning and consequently the Traffic does not work, I already mentioned this and I repeat. Not cost check your trafficprovider.xml of your country: must include Sid ltn = 1 and = 33. Another measure is you fix the radio station manually, in the option "Test RDS" which is on the screen "FM Traffic Status".
Finally, I do not know exactly why, but I also noticed these discrepancies, but with other models and GPS receivers (1300 with GTM25, for example). I decided to completely resetting "Clear all user data" (Diagnostic Page), Clear Nonvol (Developer Info \ Nonvol Statistics) and finally doing a Hardware Reset gps. I hope I have added something. In the coming days I will be off line..
Regarding the "Grid fmTunning" everything indicates that it is fixed by firmware gps based on data from trafficprovider.xml, signature, FM-RDS, and is not inherent in the model or market to which it is sold. I say this because Garmin gps bought in Europe (grid "Word") work perfectly fine here with "Traffic" in my country, that uses grid US "NorthAmerica". (Hypothesis based on observations of GPS and receivers newer (1300's, GTM 25 and above)
