I started having problems with my 62s this morning. Initially it would just turn on, start loading waypoints and then just shut off. I found a solution on a garmin forum which recommended installing a recovery file. This worked and the unit now powers up correctly. However, I can no longer get my PC to recognize the device. I have re-installed the drivers, tried a new cable and tried a different laptop, all without success.
I found a solution which recommends holding the up arrow while plugging the unit into the usb port. When I do this, the usb symbol on the GPS is displayed for a few seconds, then the device powers off.
One other thing -- When the device powers on the display shows "Invalid JNX file" with an OK button. If you press OK, the unit seems to go into normal operation(with the exception that you cannot hook it up to the computer).
Any recommendations would be greatly appreciated. Thanks.
