Took the new SL out today to break it in a bit. It was a clear sky but then quickly became overcast with no storm. My SXM screen suddenly said "Check Antenna" and I noticed all my SXM colored icons had turned black/white. Reception was still good. What gives?

PS- I have owned a Nissan Altima new since '07. It has XM and I have never experienced a problem like this. Of course the '07 had no colored station icons to begin with, but then again I never received a "Check Antenna" message ever.

Thanks,
