Bummer! Downgrading to v27.1 went perfectly.
Rebooted to OS 7.10 but with Italian Deutch and Francais options as before
So I the guess idea of getting English Language loaded on my X by way of an OS change is out

- hopefully anyone with a similar need will find this post and get the answer the easy way.
So it's either fork out for an i-bus cable and Navcoder SW, or fork out for the $tealer$ to code it to English. Either way I need to spend more time and money - shame
Thanks anyway Jochen,
