My 1995 Avant screen 'popped' last week and I've replaced it with a 2006 BV3 which, I notice, has a motorised stand connection socket on the rear. As the Avant is uneconomic to repair, it'll be offered for spares but is the Avant stand compatible with the BV3? If so, any information on how to swap it will be gratefully received as I don't seem to be able to find any references to this being done and don't want to strip down the Avant needlessly.
