yes, after importing into the LL location, restart in the LCC/83
location and run v.proj.

Only via v.proj, not directly..

But you can pass it through PROJ4's cs2cs first. see the $IN_PROJ,
$OUT_PROJ, and cs2cs bits in the v.in.garmin script; ie (generally) to
go from WGS84 lon/lat to current projection:

IN_PROJ="+proj=longlat +towgs84=0.000,0.000,0.000"
OUT_PROJ="`g.proj -jf`"

cs2cs -f %.7f $IN_PROJ +to $OUT_PROJ < infile.txt > outfile.txt


If source projection is not LL/WGS84, use g.proj to get correct input
string.

cs2cs is probably already installed on your system.
