And all this to activate functions in the CIC, where the hardware and software are already in place, but locked out. Same process for SIRIUS as expected. (CIC= car information computer fwiw, as opposed to the older version CCC, car communications computer)

I'm sure I'll get more info about this when I go for my next training course...
