I’ve got a 06 octy with a stream (non mp3), and a changer in the boot.

 

I’ve been trying to use an FM Bluetooth gadget, tried 2, both when it’s a quiet piece of music or when not playing anything exhibit a faint pop/tap noise every 5 secs approx. When playing music this distorts the music as well.

 

I understand there is a firmware update available but I’m guessing the dealer won’t do it for free now. Has anyone got a copy of it? I’m guessing it’s just a CD.

Found out what was causing it, it’s a setting called learn, it was on. once I turned it off no more distortion.

I do have a few old firmware CD's, but no idea which would apply.

 

Since fixed, best leave well alone.
