@andrus,
And when you use the tool JaVaWa Device Mgr what does it show on you unit.
Both internal and SD card????
Plus the only time you need a unlock file is when you are using genuine Garmin maps that is locked.
Openstreet type of maps do not need any unlocking file.
Post screen shots from JaVaWa Device Mgr showing your unit and the files that are in it.
The bottom line here is if your unit is so screwed up take it to a GPS outlet to get it fixed.
I would think in Estonia there must be Waypoint shops you can take the Colorado 300 too.
Spend some money on it if you really need this unit.
Try looking for Estonia forums for Garmin maybe they can help.
