EDIT to my above post, it’s not the same serial number, it’s a new unit, I’d been looking at the wrong number.Just got my replacement back today and noticed when connected to Express it’s now referred to as Navigator V1 - 1 rather than just Navigator V1.
It’s got the same serial number so assuming it’s the one I returned, which was also a replacement.
It knew my location on initial start, before acquiring satellites but wasn’t recognised by Express, saying a new device had been detected and it needed the maps/software updating.
Do I have faith in it? I’m not that daft.
