TOMTOM TMC receiver serial data format

[grazz]

Hi,
I'm trying to determine the TMC serial output from my TOMTOM TMC receiver for my car pc

I've got a standard TMC device from the tomtom 510/710/910 serial, which I've line converted the output from 3v TTL to Serial, on a scope it looks like 19200bps baud (smallest blip was ~52us long = 19200). I was expecting TMC data such as PI code, LocationID, Event ID etc as in the TMC ISO spec but instead I get this sort of data:

0d;0a;00;04;0c;00;1b;00;4f;00;10;0a;80;25;00;2a;e3;0d;0a;
0d;0a;00;04;0c;00;29;00;55;00;10;0a;44;25;00;2a;0f;0d;0a;
0d;0a;00;04;0c;00;22;00;57;00;10;0a;80;25;00;2a;c2;0d;0a;

Anyone know anymore, if this is encoded or the format of this data, i'm wanting the Location code, and Event code from this stream?

Thanks!
