you need to clear the fake FSC codes, then load the OEM codes - after that it will work again like factory.
To do this you will need a windows PC and ENET cable - of you have those I can probably help you remotely.
I've stupidly allowed BMW to update my car, and the navigation is stuck on loading. I realise now, I should have uninstalled my non-factory Carplay installation.
They advised that because I had manipulated the headset by installing Carplay it had caused the Nav to fail.
Can you advise on how to get this restored? I pay for the BMW booster pack, which includes updated maps, so it would be good to get the use of it. Will it automatically reinstall the BMW pack? I also intend to reinstall Carplay.
My argument that they should ensure that there is nothing on the system that will cause a problem, before they install updates, fell on deaf ears. And now they want to charge me to get it back to the state it was in before I gave it to them.
