From which Source do you download the Navcore? Before activating Map, do you have restart your Device (with Drum rolls) to create a ttgo.bif? Look into your Device, thats create. If you have a nonpatched NC , go in TTA to Tools and patch it, then Update Meta, then Load Europe TRUCK 1110.11883 and activate the Map. Good luck
Edit: If you load it from TT Server, the Name GO 7000 will be correct, i think

you can unpack it with WinRar or 7zip on your device, Restart to create TTGO.bif, patch it with TTA, and all other , like i say abouve
