I've got a BirdsEye experience for me old Epix model.
Have you tried to use Satelite images (BirdsEye) for Garmin Fenix 5x?
This page https://buy.garmin.com/en-US/US/p/70144#overview works for US and Canada.
Is it possible to get an EU countries link?
Could you demonstrate how it looks in Fenix 5x?
