-> are you sure about 45°N? In German Gauß-Krüger-System it is 0N.

Please send your full coordinates.
I used m.proj like this:
Please specify projection name
Initializing INPUT projection ELLIPSOID:
Enter INPUT Central Parallel [lat_0] (23N) : 0N
Enter INPUT Central Meridian [lon_0] (96W) : 13:20E
Enter INPUT False Easting [x_0] (0.000000) : 4500000
Enter plural for INPUT units [meters]:
Initializing OUTPUT PROJECTION:
Now the full coordinates would have to be entered.
Note: You enter decimal degree like 12.7639N and sexagesimal degree
GRASS is accepting both.
So, if you send the full coordinates, I will check how to convert
