After programming a couple of E60's with voice control i learned to avoid programming CCC that has FSC/BO enabling codes as i can't restore them.
Someone asked me to look at 2014 M6 that seems to have a coding error meaning the head unit does not realize it should be sending sound via amplifier.
I reckon ISTA-P full program/code should fix it but i am worried i will lose FSC codes.
Do these also vanish from modern head units like CIC/NBT after ISTA-P programming?
If i just run full car code (no programming) will this let me retain FSC? Same story if I code all modules to default using E-Sys?
