Does anyone have a MapInstall software. I used it to install all the gmap folder and other mapsource maps, with this. I just had to copy the map folder in in that C:\program data\ garmin\maps. And also have a Micro SD or ur device (it only saves in this device). Just run the map install and in 5-10 mins u'll have a .img file in your device. And u can use FIU. It was very simple.
