In Mabimods there is the minimap mod you are looking for but it is part of a compilation of other mods. Google "Mabimods"--> Register--->"Forum"--->"Client Modifications"--> "The Unofficial Tiara's Moonshine"-->"Read"-->Download--> Than check what you want and don't want. ---> Install--> Than Datapacker
The map mod is under data>gfx>gui>map_jpg>"Modded Courcle Map" if you only want that one specific map and nothing else.
Hope this helps and read the forum topic I mentioned above if you want to know how to uninstall and what each mod does in Tiara
