Hi. I have an EM-401 all wired up and am getting a good serial data stream from it (I see the $GPGCC, etc. strings). The problem is that the GMT is wrong, and latitude, longitude, and altitude are all returned as zero!
Do I need an antenna, or does the EM-401 only work outside?
Thanks for any help.
