FONA 3G SIM5320E not returning GSMLOC in FONAtest

Hi,

I've decided to upgrade from the FONA 808 to the FONA 3G and have also got the new library and code

SIM card sends SMS text okay but will not give back latitude and longitude from the 'l' command. The light is flashing fast indicating it has a lock and should return data so I'm thinking there is something with the code in the library or module code. Anyone experienced this and fixed it?

TIA

Here is the serial output

Here is the hardware setup
