Fenix topo from 66i

Hello All

 I hope everyone is well and staying safe. We are mostly in pretty good shape here in New Zealand.

i am just starting my Garmin journey and want to buy the Fenix 6. I have the 66i and want to know, as the watch I am looking at does not come with maps of NZ, can I “share” maps from 66i?

 Hoping that I can have a shave and master relationship. Or does each device have to be stand alone capable and have the maps on it?
