Hello all,
Just bought an used Etrex 10.
I turned it on, and it says it has firmware 3.70.
I don’t find anything related to this firmware.
Could it be a fake unit ?

Likely a running hardware change in production resulted in a newer firmware loaded to freshly produced units.

Where did you purchase the device?

I purchased the device second hand on Cex (store that sells second hand stuff ) in Spain.
