Does anyone know if it is possible to display position in OSGB grid on this unit?

Not looking at the specs, no.

If I may 'bend' the thread a little, briefly, AFAIK there are currently no sat navs that offer/accept OS Gridrefs as location or goto's. I believe the last was a Garmin that was discontinued two or three years ago. If anyone knows otherwise, please tell - there are a lot of potential customers still.

I'd agree with that!

My old Garmin SatNav that now won't find a sat. signal certainly did have OS GR's as I used it a few times geocaching. Now I've had to go back to my handheld Garmin GPS receiver.

Have you posted this question in the ICE Security and insurance section as well?

Not as yet but will give it a go - I suspected that it was not possible but always worth a try.
