ArduIMU not getting a fix

Hi all,

After spending more than 2 days trying to get my EM406A work with my ArduIMU (v1) in binary a finally gave up.

I reset it all as an NMEA gps at 38400 baud and made sure I had a working GPS that got a fix using a terminal prograjm. 

I ran the IMU in debug and got the following output with the GPS by my window.

!!!VER:1.8.1,RLL:-0.06,PCH:-0.05,YAW:5.70,IMUH:253,LAT:546332616,LON:-35521700,ALT:405,COG:78,SOG:0,FIX:1,SAT:6,TOW:20424300***

I then turned debug off and set for binary output. Taking the IMU outside it then acquired 8 sats (using the killmore test program), 

Unfortunately the little blue LED will not stop flashing.

Does anyone know why the IMU recognises the data but will not recognise a fix?

Any help would be great.

Many thanks.
