Hello,
I bought an old Etrex summit, the internal software version is 3.10. I cant upgrade with webupdater, it says me that there is no recent version of firmware for my device.
When I look to the version number history on garmin site, I can see the 3.7 version but no 3.1 version. Perhaps the previous owner flash the device with a Summit HC firmware ?
Could I force the 3.7 firmware by using the .exe file from windows.
Thanks very much for your help or comment, sorry for my bad english (i m from France)
Christophe..
