How to sync signature in Garmin 735XT

I am happy I don’t have to update Xert Code manually for each data field no. I have already loaded my Xert username and password in Garmin Connect Apps/Datafields, but I don’t see the update in the unit. My current MPA is 944 and the unit (735XT) still shows an old value of 970. I sync the unit to the phone with Garmin Connect, but steel don’t see the updated signature… any thoughts? Recommendations?

See our FAQ on how to configure the new datafields. The process can be a bit finicky.
