it is better to create a new lat/lon Location than to try and convert a simple xy Location into a lat/lon one by hand. all maps within a single Location will share the same map projection. You can't mix and match (lat/lon uses a radial coordinate system; simple xy uses a Cartesian one). after importing into a lat/lon Location (with '-l') be sure to double check map bounds with r.info, and fix with r.region if needed.
