Im receive reply from SEAT that I can by MAPCARE(Im send them reference number 000060884 and they find option) but I must drive car to dealer that they activate them by tester...
I will go that route and save headache with retrofiting options...
Thanks for your help and provided informations.
It is the safer option and less stress. Shame Seat UK don't offer Mapcare here then you would just buy it from the start at the nominal amount. Obviously Mib2 version of it.
