I'm not sure what you mean with your first sentence (not hearing from CF, except updates), although I could think of some educated guesses...
If you mean real updates, than I can say that I'm working on an update for Centrafuse Auto right now. This update should solve some known and unknown bugs and some new features. We are also expecting some performance improvements. Can't say anything about a planned release date now, but I'm aiming for a Christmas surprise.
Strange however that a new cable changes the behavior of the radio; did you perhaps also updated Centrafuse or the HDRadio module in the mean while?
I'll take my good old CarTFT FM 99 module and put it on test again and see if it auto-starts with Centrafuse (as soon as I have a working version of Centrafuse again (I'm in the middle of an update, replacing the XML reader).
