Fabia 3 - Cruise Control Retrofit

I am about to retrofit cruise control on My wife's Fabia 3.

The car currently has speed control and I have checked that the BCM is correct.
I have the genuine cruise control kit from Skoda which comprises of the new stalks and activation software
The activation software with the kit simply gives 3 fields as follows:
1. Activation code
2. Activation Number
3. PIN code

I have a Ross-Tech HEX-V2 kit which I will be using for coding - hopefully

Can anybody offer any advice / instructions

You cannot activate it with VCDS. You need to take it to official workshop as the activation is done online. They will also code it online at the same time.
