F800GS service in Northern Germany?

[niklasthedolphin]

Can anyone recommend a BMW service point in Northern Germany for a BMW F800GS 40.000km service?
Rostock, Lübeck, Flenburg or similar places with easy access from Denmark by ferry or from across the Jutland border.
Any idea on price for this service in Germany?
