My Garmin Etrex was working fine and without any reason it wont turn on on batteries anymore. When I press the power button it shows the garmin message but only for a second and it does not beep, and then it turns off.
But when I connect it to the usb external power it works fine.
I've checked the batteries compartment and it is clean and in good shape and the batteries work fine on other etrex gps.
Is there any way to do a full reset to factory defaults. I don't care about the data on it.
I have the same problem. The unit works until I connect it to whatever computer via USB (Mac or PC). The screen blanks out as soon as I plug in the USB cable. I have to disconnect the device and only then I am able to turn it on again. That started after Firmware update from V 2.90 to 3.00 . I am not sure this is causing problem. What about the firmware versions of your devices ? Are they all on the latest ?
However, does anybody know if there is a way to go back to firmware version 2.9 if it is not possible anymore to connect the device to any computer (evtl. through putting data on the microSD card ?).
Thanks,
Martin

Garmin eTrex will not turn on. I had been using it for a few hours continuously while hiking and then it just went off and won't come back on. When I press the power button it shows the first Garmin image for less than a second and goes back off.
Works fine on it's own battery, but cycles when plugged in
