Heres what I found. Issue: repeatedly getting updates to an uninstalled app which somehow was still in the registered apps list. Solution: I had to go to GARMIN CONNECT (ON THE COMPUTER), not mobile! Under devices and sunc status hover and drop down (top right icon) I could see the offending app listed aith a cross to remove it.... viola! offending app now removed from updating list despite app already being removed from my Garmin device. No more failed updates.
