How to access the map? Ultima VII - The Black Gate

Hello,

I have been relying on the interactive map on the internet, but I don't know how to access the in-game map. I bought some item in Trinsic called a "sextant", but all it does is tell me the coordinates I'm in, instead of showing a world map. Is there any way to get or to access the world map to know my location?

Please help.

I didn't find the right solution from the Internet.
