Question Dual Tuner radios and "cracked" RDS

Does anyone have a list (or an idea) of which cars come with the dual-tuner radio, and which ones have the older single tuner?

I'm assuming all iDrive cars have dual-tuners, and that X3'07 have the new BMW Radio 54 with the dual-tuner. I know my european X3'06 with navi profissional has only a single tuner, but I think I read somewhere in these forums that the USA models have dual-tuner.

This is related to some news about "RDS/TMC" being cracked. Nothing to be scared, as it's not that easy to do the attack, but i'm still wondering which cars could be affected.
The news are at News Yahoo / PC World and my take is at my blog

That's not "cracked".

Since whaen is broadcasting a standard RDS signal a "crack" ?

The RDS standard is documented and freely available, the TMC standard likewise.

It's not exactly a secret. Anyone can bolt together an RDS transmitter and transmit RDS-TMC signals.

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...
