[GRASS-user] Trouble with ESRI TIGER/LINE Files and Coordinate System

I have downloaded several files from the ESRI TIGER/LINE database. The site
claims that the files are in lat/lon NAD83 format. Perfect! I assume this
would correspond to EPSG 4269 format.
I have tried creating a new location in all three ways: projection values
using lat/lon (using rounded values of the geographic area), georeferenced
file (the shape file), and by EPSG Code (3310 and 4269). In every case, when
I import the shape file using v.in.ogr and then display the vector map, it
is displayed in a region using some other format (huge numbers), and not in
the lat/lon format I expected. The projection even reads "x,y" even though I
selected lat/lon for the location:
-|
| Type of Map: vector (level: 2)
|
| Number of points: 0 Number of areas: 0
| Number of lines: 32493 Number of islands: 0
| Number of boundaries: 0 Number of faces: 0
| Number of centroids: 0 Number of kernels: 0
|
| Map is 3D: 0
| Number of dblinks: 1
|
| Projection: x,y
| N: -322776.48526848 S: -457156.35430172
| E: 51189.38422193 W: -59948.35401544

| Digitization threshold: 0

What is strange is that if I import this shape file into gvSIG, it reads the
map perfectly fine, with the correct coordinate system. Since the file is in
plain ol' lat/lon, it should display that way in GRASS. What am I missing??
What could I be doing wrong?
