GPSMAP 6212 Basecamp Crashes and will not export/transfer to SD Card

I have been trying to send routes, and tracks to my 6212. Zero success. The 6212 will format the SD card and create the User Data folder and ADM file.

It does not matter how large or small the route or track may be, Basecamp crashed every time when I either drag the route/track or use the transfer step to move to the SD card.

The 6212 does not seem to recognize a gpx file no matter where or what directory it is in on the SD card.

Has anyone had success moving any data to the 6212? If so could you share the secret Please?

( the original goal was to move the Bobs Tracks gpx files )

Thank you
