seems neotouch and HD2-users are all stuck, because there is no information available on how to extract the TMC-info from the chipset.
So there has been no progress concerning the two in the threads you have already linked.
What makes things worse is, that you can have RDS-Info on the neotouch
by default when listening to the radio.
So there is proof of principle, but without support from within the task to make TMC available to the device seems almost impossible, which in fact is a shame!
I would also love to have TMC available, right now the best substitute is trafficMate
, unfortunately the information can't be used by igo for instance and there will be charges for wireless connection used.
