Bob, I'm presuming you're using your 720 via wifi to do this update. It might be your card causing a problem - but it could also be your wifi connection. There are some circumstances where your 720 will drop & reconnect, causing the file being downloaded to restart. And there are a couple of large files that could cause you to get in a retry loop. Check your WiFi connections, do you have more than one with <PRE>? If so, select those and hit "Disconnect", keeping only your active network. Then try again.
Jim, Our Static Databases were last updated 7/19/12. This data does not expire - it's stuff like lakes, roads state boundaries, terrain elevations, etc. What sort of trouble did you have downloading these?
Thanks,
Walter
