Incompatible? It's always been compatible. What incompatibility was there? I've never had issues with the galaxy map. I have all the Jedi Temple/Coruscant mods installed, and never had any issues. My guess is that anyone running into issues, is either installing it wrong, or they have other mods causing issues.
My installation order: The base Jedi Temple mod, then the compatibility patch, then I add in the Coruscant Map and Textures mod (fixes galaxy map and has better textures, then the Temple Expansion, and finally the TSL galaxy map fix. I also just realized I don't have the Coruscant realistic skybox. I've grabbed that too.
Links to mod installation in order of installation:
1: Jedi Temple base
2: Compatibility patch
3: Coruscant Map and Textures
4: Jedi Temple Expansion (the link to Nexus Mods in the previous mod description is no longer usable)
5: The TSL Galaxy Map fix by Bead-V which is required.
The Realistic Skybox I'm sure can be tossed in at any time, though I like to add those last for any mod.
