Export POI from Columbus?

[rail]

I have the Columbus Infotainment navigation. I have lots of POI's stored in the memory.

You can import POI's from USB-stick or SD-card that contains vCards files.

But I want to export POI's from Columbus to USB-stick or SD-card.

So I can delete many POI's from the system and import them when I need them.

I have found nothing about this in the Owner's Manual.

I find this very strange. If you're able to import you should also be able to export.

Is there any way this can be done?
