Hi, I have a 2017 Astra K with the infotainment system, My mic doesn't work for hands free and good old Google says if you remove the fuse it resets it all, factory reset didn't fix it. I'm wondering if I do that, will I need a code for it to work again? Does it even have a code? Thanks, just want to male sure it's not the actual mic as not got a clue where to find that.
