The one station I've found so far that broadcasts in my area using RDS does the same thing to me. During the day it flashes in & out after about 30 seconds it shows the station call letters then later the clock shows up, still haven't seen any message at the bottom. At night I the RDS indicator on same station doesn't show up at all.
Interesting thing about the clock that shows up is it'll be wrong when it first appears but corrects itself after a few seconds.
