The user haute, from [Only registered and activated users can see links. ] has built a firmware that allows an eTREX 20 to act as an eTREX 30 ( No compass and no barometric pressure working as the etrex 20 do not have the sensors)

This firmware is also patched for the JNX maps
Changes are reversible with original garmin firmware
