Yes mate, it is a tricky thing, and there are a few out of date locations.
It sort of relies on the Body mod person to contact DT, or as you have just done and share the info. (even better if you now ask Aiden to contact DT with his new info / location )
There is a thread where we tried to get a community map running lead by @thunderblaster but we haven’t seen him for a while, it would be great if he came back or somebody else with the skill to pick up the reins.
At the end of the day, the DT partner map is a reference and starting point and people should always call before just rocking up.
@KaiCastledine also hosts a map that I believe is quite upto date
