Here you go fella - licence unlocked + patched hud & mirror link should also work.
If you get issues with mirrorlink - you might need to install in vendor mode (search the net on how to do that).
Install Apk - start at least once and download the maps + base files.
Once that is done, quit out of the app & close it down properly (or it will keep showing the map download page).
Put content.info into this folder: Android/data/com.sygic.incar/files/Maps
Restart the App.
Sygic Car Connected Navigation 18.6.2.zip
Do you know if this uses some external service (possibly some android system service) to download the extra files ? I've allowed it through the firewall but it still can't download anything.
