Thread: Using TMC in Garmin nuvi for free

Following up on acleite 26/08/2011 4:22 am codes...post #259
The first two codes did not work and end up hiding the TTN supplier from the FM table, and now the table changed as follows:
947, 3, 15, 0, 11
931, 3, 15, 0, 128
881, 11, 15, 0, 7
993, 11, 15, 0, 11
1065, 11, 15, 0, 11
953, 11, 15, 0, 11
937, 11, 15, 0, 125
I am currently trying on a Nuvi 660.
After I deleted the first two codes I tried the 3851,36,36,1 The code seems to work but the traffic report seems verry limited in Mexico City to the outskirts and after two days it basically reports the same traffic areas (construction zones), the Garmin traffic page ([Only registered and activated users can see links. ]) shows much more information. Some reports in the Nuvi were as far as Guadalajara and Hermosillo (very far from Mexico City).

I also checked an FM table in a Nuvi 275T and it is:

105.9, 15, 7, 6, 6
88.1, 15, 7, 0, 11
105.30, 15, 6, 0, 11
93.70, 15, 7, 0, 11
91.90, 15, 7, 6, 6
100.30, 15, 7, 6, 6
95.10, 15, 7, 6, 6
95.70, 15, 6, 0, 11
91.10, 15, 7, 6, 6
106.5, 15, 11, 0, 11
94.90, 15, 7, 6, 6

How do I generate the FID, PID, Rgn ID, VenID from this information to try to see which FM table is more reliable?
