removal of component protection (CP) would be first thing required.
a local vw retrofit place should be able to do it, even a local vw dealer could do it but they could be arsey/funny about it.
once you remove CP they unit will have no features. Main one is you lose BT.
this required me to visit my vw dealer and get them to update the unit SWaP codes so i got all the features back i originally had.
then it's just getting app connect code but i'm still not 100% sure it will accept the code then.
