As far as i know and correct me if im wrong , there are 2 names in the market who design the adapter, carsystems in Europe and bimmerretrofit in Canada . I know others have copied those adapters but since im one of the Authorized installers in Germany for carsystems adapters, definitely i use their adapter .

I also tried bimmerretrofit adapter few times due to customers requests but i asure to you, like comparing Seat to BMW [GRINNING FACE WITH SMILING EYES] .

Im not used to mention names on forums so people don't call it marketing and advertising but since you mentioned names then i share the same . [THUMBS UP SIGN]
