OK,
Did a try of reloading 9.205 again with just map, but this time without the 9.205 folder.
It operated to the 'Legal notice' screen waiting for me to click 'I agree', but when clicked to agree it turns blue and hangs. A few seconds later it reboots through to Legal notice.
Did open the 9.205 folder and copied 3 files to device and overwritten as wished. Still as above.
In both cases did run Fastactivate to get dct for map.
