That is exactly my point in my blog. Anyone can do it, but the signal would be easily catched by the public regulator (FCC equivalent).

The difference here is that if the radio is dual tuner and both channels have no RDS, it's relatively easy to convince the radio to tune in to your faked station.

Fortunately that having a single-tuner radio, or having a double-tuner and any of the tuners already listening to a RDS enabled channel, makes the "attack" unfeasible.

But my question was related to the radio 54 and which cars have that radio...
