Subscription says I can do configurations but for that i need a saved known good Softwarebase. But both options to decode the CEM PIN are greyed out? Am I stupid?! I just wanna set different wheel diameter.

Hi.
I am new to Volvos and working with them softwarewise.
Has anybody fitted a different steering wheel to a SPA Volvo?
Can somebody walk me thru what to do? I am a car mechanic on VW/Audi.
