1 Firmware update is what it has been trying to do. Lets's see if we can determine why it keeps retrying.
2 We watch.
3 Ah hah. Two minutes in, kaboom.
4 Searching on the error message leads to a doc that says you need 200MB free for an update. We have 64. No bueno. See if you have maps installed and delete some, they suggest. We do. We delete South America.
5 Deleting South America gets us 140 MB of space back and gets over the 200 MB threshold.
6 After updating, there is now less than 200 MB free. So more maps will have to be deleted if there is another firmware update down the road.
