Thread: Using TMC in Garmin nuvi for free

Caty, that info from Loly definitely should go in Post 1 i reckon.

Giomen, if you are saying you have heard that the country subscription added with "trigger=" works with GTM25 only, my tests below don't confirm that. It seems to work with GTM26 as well.

Loly, I can't believe i never realised what "trigger=" was for. I knew that the individual subscription info for States of AU could be obtained using their linked subscriptions, like this:



Silly me, when i've added AU traffic to an overseas GTM, i've been labouriously adding 8 separate ones. I have a GMT26 from a US 1450T. I've used 129 0 0 1 to generate a code for all AU, bingo got all 8 in one go. For fun, I also added a code using 132 0 0 1 for EU. Now i've got Traffic Master (UK), V-Traffic (FR), TMobilius (BE), INfoblu (IT), NAVTEQ Traffic (DE), Mediamobile Nordic (FI, NO, SE, PL), Radio SI/TrafficNav (SI), TrafficNav (HU), RTL-ACL (LU), and BeMobile (NL) as Lifetime subscriptions along with Suna (AUS) and the original NAVTEQ Traffic (US, CAN) and Total Traffic Network (US, CAN) Expires 10/10/2055. 13 subscriptions on it now, 11 added in the space of a couple of minutes.

If GTM26 also has 15 subs limit, i can still add a couple more. Added 31495 14 14 1 and 31495 15 15 1 for Brazil and got NAVTEQ Traffic (BR). 2561 17 17 1 gives me Altech Netstar (ZA). That's 15 subscriptions, getting cocky now, so let's test the limit for GTM26. Loly said he only knows for sure that it's 15 for GTM25. I'll chuck in another one...... but no cigar! That's it, it says the 16th sub is successfully added, but it's not in the Traffic Provider list, so 15 limit also applies to GTM26 and probably the others as well.

Road tests are ok with 1450, 2350 and 3790 with the AU Suna JM subscription. I can't test the other JM Subs of course. Won't work with my 2455 or 3590 as i already knew thanks to Angelo & Loly.
EDIT: The 3590 does work with the JM sub for Suna (AUS). Assumed it wouldn't seeing the 2455 didn't work. Need to sort out why one works and not the other. Maybe the JM signature works in AU because Suna only has 3 parameters in the FM Table under GTM Info not 4 as in places where there's also the ecc broadcast seek... beats me. Now need to tackle the uncooperative 2455.

Neil, when info above appeared on "known" forum the all model with support of TrafficProvider.xml be in the plans except for 1xxx with GTM25
So all GTM-recievers greater then GTM-25 work fine also! I edit my post for explanation. Thank you.
But it is not work on older model without support of TrafficProvider.xml. My remark above with quote from original source about it! For example, not work on Nuvi 765

P.S. Do you try clear FM table:
