Georectify a raster map to WGS 84 standard.

Hi,

i got a raster map (jpeg with normal xy-coords ... around 7000x7000 pix). My task is to georectify it using GRASS. I tried to set up a new location in WGS 84 standard and load the raster map afterwards. This did not work. GRASS said "Illegal latitude for North"

So i tried to a new location with normal xy-coords, now is was able to load (with "r.in.gdal") and display the map. Then i found the "i.target"-command, that will copy the georectified map in the other WGS 84-location. Sadly, this didn't work too. There was a new raster map called "...georect2128" created, but not in the WGS 84 location. Additionally, i was not able to display it. It works, but nothing can be seen in the display window (unlike the original map)

I am a total newbie at GRASS, so it would be fine if anyone could help me with that issue. Thanks in advance

greetings
