Please remember that after discontinuation of model 451, card updates will be made available.
The card updates are settled and sold exclusively through authorized smart and MercedesBenz service plants.
Settlement by an external service provider or suppliers such as, e.g. Bosch services is not possible.
It should be noted that replacement units are always supplied with the oldest card version. The latest card release must be subsequently installed.
This is free of charge for a warranty case.
