Yesterday, I had a fully functioning Garmin GPS12 running software 4.00. I went to the Garmin site and saw that 4.60 update was available for GPS12's running 4.00 or higher. I downloaded 4.60 to my PC and started the upload to the GPS12. I got a message like "upload in progress" but after about 10 minutes, the dreaded "upload not present" showed on the LCD screen. At that point the GPS12 would not function except for turning on and off with the power button and displaying the "upload not present" message. I attempted to re-try the upload but both the "Updater" and "WebUpdater" programs report that software version 3.62 is resident (not the original 4.00 or the desired 4.60) and that no updates are available for this system. So this is where it stands- no operation, no ability to update or even get back to original (pre-update) status. Furthermore, The Garmin site suggest that repair service is no longer available for the GPS12.
