did you remove the rubber mat that lines the bottom of the tray? Its just pulls out and its underneath there...

Nope! Never dreamt it would be hidden under the mat

I think I've just found it

try here https://dl.dropboxusercontent.com/u/6728431/2012 Chevrolet Volt Opel Ampera Service Manual.pdf

but be quick these things tend to disappear!

Wow, that is a large manual.
Many thanks for the link. It always comes in handy for the little jobs.

I had a quick look at the drive assembly and wished I hadn't. The Volt/Ampera may well be reliable but the complexity of the drive is absolutely scary.
To think I have been bragging for years how simple an EV is..............only an ICE manufacturer could turn simple into so much complexity.
And to think I had thought the double clutch gearboxes many ICE's have now were over complicated!

Just remembered - I once downloaded the Chevy Volt workshop manual from somewhere (72Mb and 8,000 pages) and sure enough there is a page on "Instrument Panel Upper Centre Compartment Replacement."

This shows 2 screws behind the radio / sat nav that have to be removed first - I'll try this when at home and let you know how I get on...

Thanks, glad it didn't disappear too quickly.
