[QUOTE=biggerdave;970939]Firstly let TTHome incrementally update your navcore (one at a time) until it says no further updates THEN you'll have the latest/current/official version for your device.

Have installed and run TTHome. It did a couple of small updates but did not put a later version of Navcore on device. So, still at 8.204! Should I be able to update on a TT ONE Second edition?
