Spoiler: Show
Install the archive to an empty device, if you already have an activated map on it than leave tha map on the device too, same for custom voices.
After the first start you will get a reboot - this is normal and can take up to 5min!
If after 5min the device still shows the TT logo screen than something went wrong.
The TTS voice of Susan is already included as I noticed some TTS voices are not working properly on my device using this Navcore, however Susan works fine.
If you want to test please leave in your feedback what X50 device you use, what map and if you find problems try to describe them as exact as possible.
Known problems so far : you have to hold the power button +15sec to shut the device off properly.
