Or it's simply that I made a mistake and didn't do it correctly

This what I did:

- Uploaded a cure then could check on the file that I get on system storage. Which was successful
- Uploaded a original version always by using GarminCure3 for the conversion and uploaded to my GPS...But nothing changed (Still the splash screen) and no access to storage...

By the way I just saw your nickname. Thank you for GarminCure3 ;]
