Thanks again for pointing me in the right direction, you were right. I didn't need to move the GPS but from your info I discovered that the antenna cable was running alongside the GPS cable in the Rx bay and as soon as I moved things around in there it started working again
Keen to get flying today but it's currently 43C here so I think my poor Radian may melt like Ikarus...
