So, my eTrex Legend started crapping out while hunting this year. Screen would blank out at random times. Rather than throwing the unit away, I submitted a query about repairing it with Garmin support. They wrote back to say: The issue that you are having is directly related to changes that are being made in WAAS satellite signal. Garmin is aware of the issue and has made an update available that will resolve the freezing problem that is being exhibited on your GPS. A quick fix for this issue is to temporarily disable the WAAS reception from your system setup page. This will have a very minimal effect on your GPS accuracy. Thought I'd let folks know in case you haven't used yours in awhile and find it freaking out.
