Yes, it is now working. I spoke to the Technician where I bought the unit and they said it was probably the location of the unit down in the saloon/Chart Table. They said give it some time and see what happens.
I left the radio
on and you can see the aerial icon flashing in top corner as its trying to get a fix.
In about 20 minutes, it had a position and posted it on the display.
It was a matter of wait and see what happens...in my case, it took some time but it eventually got the fix.
