Xert Code in Garmin Express

When updating the Xert Code in Garmin Express, be sure to Sync your device to have the update reflected on the unit. If you unplug and plug your device back in and open the settings for the app on Garmin Express, the values should be last code you saved. If not, then your device isn’t using the proper code.

i tryed several times to copy the code into the app but from what i can see it doesnt change anything at all ??
