Using TMC in Garmin nuvi for free

**rodolfo1971** · 1st September 2011, 02:51 AM

It seems that one of my nuvi's problem is the European grid it uses to scanner the signal - both frequencies 90.5 and 93.5 are not In this grid. Any chance of changing this on its firmware?

Well, I have a 1390T, added both 4 and 5 digits for the Brazil area, all codes accepted, but no traffic information until now.

**angelozip** · 17th August 2011, 07:26 PM

Traffic only in the cities of Sao Paulo, RJ e BH. Use only 5 digits parameters..

Here is a quote from the TrafficProvider.xml from an Israeli Garmin Nuvi 1310 or 1410, what does this tell us?

what does this tell us?

Does anyone have some information on this?

**bpb** · 7th September 2011, 03:44 AM

Israel .. please try 1036/36/36/1 at least will get TMC icon on the screen.

**acleite** · 23rd August 2011, 03:13 AM

Try 28934,6,6,1 (for the first 3)
If it does not work, use 28934,6,6,0 to delete it.

Or 1542,6,6,1 (for the first 3)
If it does not work, use 1542,6,6,0 to delete it.

PS: These numbers were based on your FM TABLE. May not be because the CC of Mexico is 15 and your table shows 1 (first 3)

**oski** · 26th August 2011, 04:45 AM

I tried both sets that acleite provided on 23-08-2011 02:13 AM and only the second set worked, the CC was transmitting as 1 and not 15. Now the TTN broadcasts have disappeared.
The unamed provider is still transmiting. Any suggestions for the last 4?
Frequency, VC, CC, LTN, SID
953, 10, 15, 0,128
993, 11, 15, 36, 11
1065, 11, 15, 36, 11
987. 3, 15, 0, 16

**acleite** · 26th August 2011, 05:22 AM

Try 3851,36,36,1 (3851,36,36,0 to delete)
This uses the correct CC, which is 15 for Mexico (as i said before)
Working or not write here the result, okay?
good luck

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?
