GPS problems C027

Working on an application using the C027 Support library, but I cannot get a lat/long from my device. Even the Support_Test application does not receive a GPS signal - it enters the last conditional of the gps loop: (gps.getNmeaAngle(1,buf,len,la) && gps.getNmeaAngle(3,buf,len,lo) && gps.getNmeaItem(6,buf,len,ch) && ch == 'A') {

I've got the SARA-G350 version. I've had success with SMS and writing/reading with TCP sockets, but the GPS is not functioning - can't get a lat/long out of the GPSSerial or GPSI2C classes. Any ideas? Here's my gps.getMessage() return:

I'm at about +42, -71.
