Also, it is very easy to do something wrong and brick your device.So for the time being its hard for anyone to do it. You need to be familiar with shell scripts, android internals and so on. Also, at this moment you also should disable WAPR, that causes significant increase of head unit start time.Īlso it is possible to install any other navigation software (including 'right' versions of iGo software), but this is also very complex task at this moment. You need at least two head units of different regions to do this. It is possible to hack this system and upload fresh maps for any region, but this is very complex task and it's hard to do this. But you can not use any uploaded maps using testmode or using naviextras toolbox without proper licenses for your device model/region or for you device's id. It is possible to cheat naviextras toolbox and upload your own files without using testmode. Also, it is very easy to do something wrong and brick your device. Just for example: EU version of F960BT with maps of Russian Federation (not included in default maps set):Īlso it is possible to install any other navigation software (including 'right' versions of iGo software), but this is also very complex task at this moment. Also, at this moment you also should disable WARP (like hibernate function in windows), that causes significant increase of head unit start time. But there is a way around this problem, you also need to be familiar with many things like md5-checksum calculation, editing files in right encoding and so on. Both naviextras toolbox and headunit's synctool will refuse this. update: Also, synctool folder contents is signed with md5-checksums of files, so it is impossible just to rewrite or add your own contents. If we can get all the maps and licenses into one synctool folder, we can install the world map on any device that uses igo primo.

My idea was to trick the system and install other maps from 'sync tool' folder that naviextras toolbox create from various igo primo systems. All I'm trying to do is helping others by trying to solve this problem until there is a testmode.
