ok, here is more on the subject...
there is a member, who lives in UK and had to replace his factory radio (presumably a BM54) with a slightly newer one from US (presumably BM53). He had changed the coding to Europe from US, and he HAS the TMC active and functional on his MK4 nav system. However, when he tunes off the radio, the TMC icon goes from green to red, reconfirming the suspicion that he has BM53 unit from the US with a single tuner.

This theory can be tested with existing setup - I know I have the BM53 radio, I know I have the disks with TMC info, supposedly the TMC standard is the same worldwide, so, I just need to flip the radio from US to Euro mode...
However, here lies the problem... I do not know what version of BM53 I have, but the service menu does NOT have the Europe available under service menu...
Anyone ran into this situation?
