@jsrd: Let's continue the discussion here. Do you know the socket # where Connector 6 (TMC cable) goes into? does it connect to the MMCS directly?

Looks like the 2 sockets where the Euro TMC cable is suppose to go are non-existent in the US MMCS (in red). Does anybody know what goes into the round port (green box)?

Maybe we can directly solder the leads of the TMC cable to the PCB. It's actually easy to solder. I think the challenge is where to get the cables, and also if we can figure out where the "other" wire from the GPS antenna go into. And the last hurdle is if it's possible to program the ETACS to enable the TMC feature.

Hey rcpax, in view of your find in the back side of the MMCS, I believe complex that we could enable these functions in ours equipments, I hope that more information flows to have the certainty of this can work [sm=smiley2.gif]

hi everybody
i'm also deeply interested in enabling rds feature in my mmcs. please see a screenshot taken from service manual, i hope it will help. i'm not sure if it also refers to rds, i think that rds signal is picked up with fm signal and then decoded in radio receiver. taking under consideration that us and eu mmcs are identical (?) question is what to enable it? is decoding taking place in build-in chip (radio processor) or it is provided by software (loading.kwi)? any ideas?
cheers

Thanks for bringing that up. I think TCM and TMC are both different things altogether.
A good backgrounder I found: http://en.wikipedia.org/wiki/Traffic_Message_Channel. So it looks like the TMC signals can be broadcasted both from FM-RDS and Satellite, which would explain why there are two cables from the EU SAT Ant, and then there is another TMC cable in addition (Cable #6), which is I think for FM-RDS reception.
