It may also be the station(s).
I believe RDS pertains to analog only broadcasts & HDRadio is a different signal, but I'm nit entirely sure.
Houston has several HD channels.
Occasionally, I notice that a station refuses to update. If I switch stations, I get updated info & if I switch back to the original station, I get the same, outdated info that I saw before. That seems to indicate that the radio is fine and the problem is in incorrect data (or perhaps missing data) in the transmission.
In other cases, I've noticed the info showing a song 30-60 seconds before it starts. i.e. before the current song has finished, I know what the next song is going to be.
I don't know what's involved in keeping the analog RDS and HDRadio info synced, but there is bound to be room for hiccups.
