Are you talking about the roof, or am I missing something? Your car already has Radio Frequency Locking (RFL). Do you mean you want to operate the roof with the remote key? The R170 doesn't support that function.

As far as operating the Vario-Roof while driving, all factory systems cancel roof operation if wheel speed is detected. I've heard that some after-market systems allow this, but I'd never operate the roof while moving. You're just asking for trouble.
