Can they be switched ON and OFF from the buttons in the car? Or once installed the odometer doesn't count and I need to remove them from the car to have the odometer working again? This question is for both Mercedes and BMW settings.
Second important question is, does the speedometer work when this device is installed in the car? Again both for BMW and Mercedes settings.

Hi, speedodometer works normally after installing CAN Filter. CAN Filter is designed to support old mileage data blocking on Mercedes-Benz vehicles. It is designed to prevent regeneration of the old mileage state in vehicle dashboard (odometer). CAN filter doesn’t interrupt any vehicle electronic system, there will be no errors or DTC’s after install.
Any questions feel free to contact us.
Best regards.
