Visited Kalu today to fit my highline dash.
Had originally planned to fit a non-gti highline dash but Kalu had a spare HL from an Edition30 so optted for this instead. Tried fitting my MF buttons but looked as if they are incompatable with the newer RCD510 as theyre the older moulded version, or worse, may be faulty
Will have to try them with my old RCD500 before selling them on, along with the non-gti highline dash.
Thanks again. Very knowledgeable.
