It's in the TSB as liked to in that thread.
Ah thanks, sorry I didn't scroll whole thread just saw the other thread!
It'll be interesting to see, I'm not sure whether that is just unclear messaging in the TSB. I could read that like they are talking about the new part being the thing they are referring to there, not a new model.
To me, a GRMN already exists and I can't see them making a different GRMN, so surely the part would be in that car already if they altered it? I dunno, seems weird to me.
