Anyone know anything about the weather band radio?

I have this feature on my current 1998 540i and I use it all the time. It is tuned to the local NOA station and gives 24/7 weather forcasts and storm warnings.

It doesn't seem to be available on the US versions of the new 545i. My dealer says it isn't available any longer.

What is really confusing is that it is described in the owner's manual that is posted on this site under the radio section!!! What gives??
