Hi Gustavo!

Import your point vector map (the way you did but) in a (grass-)location
defined by its coordinate reference system. 

Then reproject (v.proj) the other vector map from "its" location to the
location you created for the point map. Or the other way,
"pull" (=reproject) the point map to the other location.

If you already did that, then maybe the maps are not meant to coincide
since you can define a grass-location by one and only one coordinate
reference system.

All the best, Nikos
