[MTCB Software Development] dsa8310:
Probably you did not preserve the "original" ID generated by mtcservice, and set via its xposed module.

I would uninstall TT. Then I would even format (clean) the data partition in the recovery menu (the entry before the last menu item). Then I would reinstall TT, and this time I would write down the serial ID generated by mtcservice, for future use/restoration. I would also install the big TT maps on external storage(create, say, folder /mnt/external_sd/tomtom/com.tomtom.gplay.navapp/foobar before reinstalling TT (on the GPS card)).
