Interesting the
2023.10 NTU don't work.
Kenwood only updates it's maps annually ,as updating a Vehicle head unit is not as easy as others which are updated quarterly ,but
2022 vs 2023.10 is confusing ,Garmin has got ahead of in naming it's map series.
2023.10 is really from the first quarter of 2022
