Hi, this most likely mean the device non-volatile memory has got corrupted.

You might want to first try rebooting the unit once or twice: open the settings, change the TCAD option for example, select 'Apply' to reboot the device in-sim. Do it again to restore the TCAD setting and reboot a second time.

If it doesn't solve the problem, the only way to 'fix' is to rebuild the non volatile memory file. This stores the device settings, preferences, user waypoints, route catalog etc... and these will be lost in doing so unfortunately (hence the benefit to edit user waypoints and routes in files, and use the device import function. NB: you can export the existing routes to file with the GNS V2 prior re-building the nonvol file, so that once done, you can re-import them back!)

To rebuild the nonvol, just delete the device nonvol file:

Model 5XX #1: "C:\ProgramData\Garmin\GNS Trainer Data\GNS\sys_nanda"
Model 5XX #2: "C:\ProgramData\Garmin\GNS Trainer Data\GNS\sys_nandb"

Model 4XX #1: "C:\ProgramData\Garmin\GNS Trainer Data\GNS\sys_nandc"
Model 4XX #2: "C:\ProgramData\Garmin\GNS Trainer Data\GNS\sys_nandd"

thanks for your help, deleting the sys_nanda files dit the trick!

Problem solved
