XM - no longer offered?

[Street Broiler]

I just did the "Build & Price" function on the official Corvette site, and noticed that XM is no longer mentioned in the options. In fact, both audio option descriptions have a double comma ", ," as if something were deleted. Can someone shed some light on this?

It's part of 2LZ, or if you don't order that you can get it standalone (U2K) in combination with the radio upgrade (US9).

Thanks. I checked but it is not mentioned anywhere under the 2LZ option. I could have sworn I saw it listed there (or in the audio options) before. Must be losing my marbles.
