i think, you need at least to associate with the ap, ie use iwconfig to  
set the ap and maybe the channel.

not sure, what you're talking about -- wifi or gps?

- check whether wifi and gps are enabled
- make sure you got a recent kernel (ie one that includes the gps fix,  
_not_ the one the fr came with)
- make sure you are in a spot where gps works! use a second gps device to  
check, if possible
- do iwconfig eth0 and check the output, do iwlist eth0 scan and check the  
output. if you see meaningful lines (with an wpa nearby you should see it  
as well), he wifi hw is ok
- do
echo 1 >  
cat /dev/ttySAC1
and watch the output, after a while the should be lines with all fields
