Use 7-Zip to extract the downloaded files. You are looking for a folder called content or individual files like USA.fbl . Do not simply drag and drop ZIP files into the IGO folder; the software cannot read compressed maps.
Upon launch, IGO Luna should say "Updating content" or "Checking licenses." If it loads to the main map screen without an error saying "Please insert correct SD card" or "Missing maps," igo luna maps install
A: Not directly. IGO uses "Here" maps. However, conversion tools exist, but they are unstable. Stick to native IGO .fbl files. Use 7-Zip to extract the downloaded files
Always virus-scan downloaded content. Map files (.fbl) are generally safe, but executable .exe installers from unknown sources are a risk. Upon launch, IGO Luna should say "Updating content"
And if the map was wrong, well… he knew where the forum was.
Copy the .apk installation file to a location you can easily find on the device.
