BMW E64 M6 Convertible top opening and closing with a remote 630 640 645 650

Garage kept. Still smooth opening and closing after 20 years of service. Hot and humid or heavy rain all year round has not permitted open top cruising very much.
The car thus accumulates only less than 70k kilometers 😀

Very clean car. Did you install an aftermarket module to allow it to work with the key remote (and if so which one?) or were you able to program it in?
