I've been doing hobby electronic assembly since valves were the norm. Despite having correctly assembled, tested, verified and reverified the soldering in my replacement PCATS tuner I still cannot get the auto frequency part of RDS to work. The tuner stubbornly sticks to one frequency even when it fades right out and there's a much stronger alternative of the same broadcast available. I seem to recall it worked properly with the original tuner but it's been so long I can't remember.
I made the move from V2.01 to V3 alpha 11 firmware to get the retune button functionality back, thinking this might also have an effect on RDS. It didn't but at least I can now easily change to a working signal again.
But V3 seems to have introduced another nasty problem not mentioned in the release notes. Often when turning the volume down it instead goes up - and keeps going up all the way to the end stop - even when the control is no longer being turned.
