Hi all. I replaced the ccc head u it after a failed.recoded u it and all working well except there are no rear sound. Have adjust sound in head unit to rear but no difference.
Testing the speaker through the software all speakers are working and sub aswell.
Unsure what to look at for this as not a heavy user of the software

If the front speakers are working just fine, then check the amp in the boot for any signs of water ingress (especially if this car is a convertible).
You can also try a reset of the CCC by pressing and holding the volume and two eject buttons.
