Success ! Yay !
It was the 'resizing' part of the SD Card format that I must have skipped in error.
It still took me a couple of goes.....but I got there eventually.
Thanks to everyone for your help......Brilliant !
And thanks JC for your offer too.
I'm now seeing my Pilotaware on my wifi.......so the next step is licensing and config.
That'll be fun - for later. 😉
All the Best.
