I've downloaded the gmapsupp.img (from post 1) and copied it to my device, removed old gmapsupp.img from the device. Is this OK, because i'm confused after reading post 5 about install.bat as there is no install.bat in this rar file. Apparantly there seems to be no problem with this file on the map and voice navigation is also fine and no error msgs also but do i have to select manually this map from device which i copied to my device?
