Basecamp on new laptop with Windows 10 Creator

Nuvi 2529 ver 8.70

Plug in nuvi to new laptop, download Garmin Express, install Communicator, check for updates, and transfer maps to PC, Basecamp will also be down loaded and installed. (updated to 4.6.2)


However, under "Manage Map Products..." UK and Ireland 2018.20 displays "Locked" and I am unable to use the maps on my hard drive.

I try "Unlock Online", "Find Device" and I enter the serial number, but I don't have an "Product Key/Coupon Code"

Is there a simple solution ? Or is this how it is meant to work?
