ID5 Evo Map upgrade

[alexgx]

Hello,

I have e BMW F31 with a ID5 NBT EVO S19322I without a valid FSC, I would like to know if I can update via USB with a valid FSC file and new maps or I need an ENET cable. I read that with the S version the usb cable is generally needed but I am not sure if is needed just to update maps. Is there someone that can supply me what is needed?

Thank you very much
