Why not Dacota? Quite simply, I did not want a touchpad, as I believe that are difficult to read because if you always rumdrückt with your fingers. Why not Etrex 30? I need neither altimeter nor compass, or was not worth my money. Firmware: The unit was shipped with the FW2.90. After several re-routing the unit is "stuck". After switching to the FW2.80 is resolved. And since, according to amendment details the changes to 2.80 mainly refer to compass and altimeter does not bother me. The service is perhaps not for everyone, but I get along well with it.
