They added my Unit ID yesterday. I had called again to follow up. Think they just did it while I was on the phone. Probably got tired of me following up. Support person was great. He patiently waited to make sure all was good while I redownloaded xml file from car and updated the Garmin Express program to newer version on pc and then started download of maps. Once going, we ended the call. Download from their server took less than 30 minutes. Install to car was about 15. Now on version 2020.10. Drove over one of the redone NYC bridges and it is now updated on their current maps. No more driving through the water. Yay!!!!
