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.

Probably best to look through any vehicle documentation to see if there is any mention of a code.
Although a lot of systems don't have them now as the audio is coded through the CanBus network so it will only work on that particular car unlike the old days of stealing one and fitting into another car with or without a code.

 

I have the same issue and I would like to hear on how you fixed it. I bought 2017 astra K recently and I have checked with both iOS and Android devices and it didn't work in neither of the devices. 

I tried to disconnect the battery terminals and reconnected it back and still the same issue. @Mellie1968 Did you manage to fix it?

Hi, It turned out the microphone was missing, I got a new one from the scrapyard and all was well. It hadn't worked since I got the car so it was obviously taken out for another car.

@Mellie1968 Yesterday I opened the courtesy light unit to my surprise it's missing in my astra K as well. I have bought one from ebay and hoping to get in next couple of days. Thanks for replying @Mellie1968
