the rds on my screen is pretty messed up and doesn't scroll like i think it should, my family has a pontiac vibe and envoy, both with RDS and it works fine on there...(even the ipod attatchment i have the emits RDS). Anyone know a solution? i dont understand why pontiac and gmc rds works and cadillac works likt sh*t.

What year is your CTS? I have an 03 and the RDS on my radio kind of screwy too. Sometimes it will display the same artist info on a station for days on end.

my cts is an '07, i just got it 3 weeks ago, this is the only problem i have with the darn thing

I too am experiencing this situation. Wonder if there is a way to reset. Will talk to dealership.

No problems with my '04 :)

I think mine has a problem. I never really see the information other than "WMMS" on there all the time. This happens even when I'm on other stations. I don't use radio much, but it is kind of weird, like it needs to be reset or something. I am positive the stations I am going to support RDS information.

I have a 06, same problem, sometimes it scrolls a lil info then none, if I turn the thumb vol on the sterring whell it brings back the call letter of the station. I have XM so I dont listen to FM much but I would like for this feature to work
