'GPS Module Not Responding' denotes a communication failure between the antenna and the unit and can be the result of a power failure to the module or a fault in the module itself. The LGC software update to which you refer included enhancements which enabled the antenna to re-set itself after being hit by radar and later modules had additional shielding.

'Position Lost' means the satellite link has been compromised. Looking at the picture it could possibly be the installation and the first step would be to try to re-create the error with the antenna positioned horizontally and also 'Require WAAS' must be disabled in 'GPS Set Up' .

You should also consider installing the latest software version for the LMS520 which is 2.3.0 released on the 10th March. The antenna should be running v.1.9.0 and information on this can be found in your device list under 'NMEA2000' (Networking)

The error is Position Lost.

I think that makes sence, I will move the antenna on to the grab rail infront of the screen and make sure the WAAS is off.

Thanks to you all for your advice.
