I've owned and updated CNNA maps to my PC and Montana many times since 2011. With latest 4.0.19 update, I keep receiving "...error installing update" red ribbon after step 2 and elevated download kicks off. Doesn't appear install even starts the download. No error details are provided so blind...
I've removed the device from GE, rebooted and re-added, and re-registered a couple times with same error...Device is registered on mygarmin with lifetime updates. Used same email address as mygarmin for the re-registeration on GE.
Here's a screenshot of error:
Any suggestions?
