Beta version in copy/paste format, it means that you just have to extract folder from compressed file and save it in PDA's SD card. To start the program just execute Twonav_Pocket.exe file inside that folder.
Note: If there isn't any Vmap inside default maps folder, Onroad/Offroad selector will not be shown.
Alert! If you copy/paste over old version of TwoNav you will lose your saved data.
