Bringing this one back to discuss an incident with my 60CSx. On a trip to the east coast and it died. Not dead dead, just wouldn't receive any GPS sat signals. . . Hmmm. Emailed Garmin and they sent me to a menu I hadn't seen before that was showing software version 0.00 . . . Hmmm again.

20 minutes later I'd updated all the system software from Garmin's website using their Updater. When I took it outside I soon had lock on seven satellites with two more being processed -- working great again. I have no explanation for why it dumped software, but it was an easy fix.
