How to upate igo maps on car navigation head unit?
Updating igo maps is very simple, newer map files are located in content folder, including building, map, poi, speedcam and other folders. The new igo maps should have at least 3 folders, building, map and poi. The most important igo navigation update file is the .fbl file in the map folder.
Firstly check what files or folders you have for new igo maps in your igo navigation sd card or the internal storage of your head unit. If there are only 3 folders:
building, map, poi
Then you just need to delete all files in the same folder from your old maps, so delete all files in folders including building, map and poi;
then copy new ones into the same directory, that’s all.
Of course, if there are other new files you can also replace the old ones with them.
