GPSMAP 65s. Internal Memory deleted. Any idea how to solve that problem?

Dear All,

unfortunately I've deleted the internal memory of my brand new GPSMAP 65S. The internal memory now shows no directory or file.

The device can be started, satellites are found, but the software remaining on my device does not allow any routing or functionality needed.

Can anybody help? Please apologize my worse english...

Kind regards,

Karl, Germany
